\?‍ ❄️ Patented technology smartphone band?/

July 14, 2025

 Introducing the very convenient ❣️ [Hammo-kun]? ? ♀️?

Did you get it in the Coetas monitor campaign?

Your hands holding your smartphone get tired, or you almost drop it inadvertently.

Or do you accidentally drop it on your face?

I have...? It hurts...

It solves such a problem in one shot.

This is the smartphone band "Hammo-kun" with this patented technology!

Truly a finger hammock "just hook your fingers" for stability

You can have a smartphone❣️

When I went to play in the river, it was stable, so I put my smartphone in the river.

I didn't drop it, and I didn't feel excited.

Easy ✨ to put on

Put the silicone band in the camera hole of the phone case and the camera hole (cable hole)

Just let it through.

Since it's silicone, it stretches, so I was able to put it on easily, right?

Even if you use it while sleeping, you are worried that your smartphone will accidentally fall on your face.

It has decreased significantly (this is really helpful!)

It's easy to operate with one hand and prevents it from falling.

It protects your important smartphone.

Once you use it, you won't be able to let it go, right? ✨

Please try using it too? ?

This is a review about the Coetas monitor campaign ([Patent Smartphone Band] Hammo-kun)

I tried Hammo-kun.

This is a patented* smartphone band that supports the prevention of smartphones from falling and making them easy to hold.

*Patent No. 7351074, international patent application (PCT/JP2024/020676)

The packaging is simple and easy to use for both men and women.

The band part has a solid material feel,Just put your finger through it and your smartphone will fit securely in your hand.

The great thing is that it can be used on a wide range of models because it can be fixed simply through the hole in the case on the back of the smartphone.

Above all, there is no need to attach it with tape, so the case does not get dirty, and it is nice to be able to easily change the case.

When I actually use it, it becomes easier to operate with one hand, and I feel that I have much less to worry about dropping my smartphone while commuting or on the go.

The band is soft and fits your fingers, so it doesn't hurt even if you use it for a long time.

It was stable when watching videos and taking photos, and it was convenient to use it as a smartphone stand.

I find it especially useful on days when I have a lot of luggage or when one hand is blocked.

It is recommended for those who want to improve the ease of holding their smartphone or those who are looking for anti-fall goods.

A smartphone band that looks like a stable hammock

July 12, 2025

In Coetas' Monitor Campaign

[Patent smartphone band]

I tried ✍️✨ it

❁.。. ✽ Impressions ✽.. ❁

I changed to iPhone 16e last month?!! ︎

What to think about changing your smartphone!

I don't want to drop it on Zettai. Want to avoid screen crispness? I bought a screen film,

I was thinking about a smartphone ring, but I tried using this patented smartphone band Hammokun!

This product is swaying in a hammockIs it a comfortable smartphone band that you can use?

Is it recommended for those who were not satisfied with conventional smartphone rings and smartphone bands?

Hammo-kun uses thick-walled silicone rubber that is comfortable to use and durable.

And! It is easily detachable and does not glue, so

Even if you buy a new smartphone case, you can continue to use it as long as the size fits! !

If you try it right away!

Is the wearing time about 1 minute?

It's more stable to hold than a strap, fluffy, but holds firmly!

Easy to use than smartphone ring! (This is my personal opinion)

In a hard case

If the camera part is wide open and the size fits, you can use it!

On the other hand, if it is a silicone case, is it curved?

The softness and hold that you can't experience anywhere else are interesting in a good way, and it's a pleasant item to use!

Thank you very much for this time.

Comfortable phone band

July 9, 2025

I tried using the patented smartphone band Hammokun.

This product is a comfortable smartphone band that can be swayed by a hammock.

Recommended for those who were not satisfied with conventional smartphone rings or smartphone bands.

I accidentally dropped my smartphone and cracked the screen.

If you can't use your smartphone, it will interfere with your life.I was thinking of attaching a smartphone ring.

Hammo-kun uses thick-walled silicone rubber that is comfortable to use and durable.

It is easily detachable and does not glue.

Even if you buy a new smartphone case, you can continue to use it as long as the size fits.

I tried attaching it to the case, but it was easy to attach by simply passing the bunt through the camera hole and fixing it with metal fittings.

The silicone rubber feels quite solid.

There are handmade leather and denim, but I chose denim, and it is simple and feels good to the touch.

You can attach a can badge, so you can enjoy a stylish look.

It is easy to hold and the risk of dropping your smartphone is likely to be reduced.

I really liked it.

Hammo-kun is a smartphone band with a completely new structure that was unlikely, and it seems that he has obtained a patent 7351074.

It also supports wireless charging, so it's good for those who want to enjoy their smartphones comfortably.

This is a review of the patented smartphone band: Hammo-kun that I received from the Coetas monitor campaign.

・・・・・

Do you have a smartphone?

Have you ever dropped it and broke the screen?

I want to have a smartphone.

It's no good to drop it. Absolutely.

I would like to recommend "Hammo-kun" to such people.

"Hammo-kun" is a band that can hold a smartphone firmly. The band itself is soft and designed to prevent damage to the hand being used.I have become a thought.

This time, we will introduce genuine leather specifications. Denim specifications are also available separately.

Attach this to your smartphone case and use it.

As a caution, it cannot be used in soft cases.

It is attached by hanging the end of the band on the hook on the opposite side.

Therefore, it can be put on and taken off at will.

Once you put it on, it doesn't stay the same, and it's convenient.

It also supports wireless charging.

I will attach the case with "Hammo-kun" to my smartphone. There were no problems such as getting stuck.

It's a style where you put your hands on a band and hold a smartphone.

I actually used it, but it didn't hit my hand strangely. You can hold it without feeling uncomfortable. There is no constriction, and the softness of the band creates ease.

One of the points is that it has been tested for strength and durability, and it is highly durable.

High quality is an important factor, so I'm happy.

The installation instructions say that the band is connected through the camera and cable holes in the case, but in this case it did not arrive. Therefore, through the fingerprint authentication and cable holes, it was just right.

"Hammo-kun" may not be able to be installed due to the length between holes. There are other precautions on the sales site and official website, so please check before purchasing.

This time it was an introduction to "Hammo-kun".

(The information posted is from the time of first posting.) Please check the seller's announcement as it may be revised.

In addition, the images used this time were created by the poster, and the feeling of use is my personal impression)

No need to worry about dropping your phone

July 7, 2025

Even if you use it for a long time, it does not put a strain on your fingers.

This is a smartphone band that uses patented technology that allows you to hold a smartphone.

The fabric for the handle is cowhide and denim, but I chose denim fabric.

To use it, pass the silicone rubber through the camera and cable holes of the smartphone case.

It is easy to install as it only needs to be fixed with metal fittings at both ends.

I tried using it when taking pictures,

thicknessBecause it is fixed with silicone rubber with

You can take beautiful photos without blurring.

If you take a photo with one hand, your hands may get tired because you feel like dropping your smartphone.

If you use this smartphone band, you don't have to worry about dropping your smartphone.

It was also good to be able to take pictures with peace of mind.

The denim fabric and silicone rubber are very solid materials, so I'm happy that they can be used for a long time.

It depends on the smartphone case.

July 7, 2025

The idea is great! It also feels good to the touch! !

However, the size is right, but it seems that my case was the type that fits perfectly with smartphones...

When I installed this, it became thicker and I didn't get into it neatly.

Sad. But it can't be helped

Prevent your smartphone from falling!

July 4, 2025

Drop prevention band attached to your smartphone! !

Is there a lot of rings in the common fall prevention?

I often attach it with adhesive tape or glue on the back, so I was worried that the smartphone case would be damaged, and I was worried that it would become sticky if I didn't like it, or that it would come off and fall off if the adhesive weakened.

This is no glue or sticky! A smartphone band that is used like a hammock on a smartphone case.

I was able to install the iPhone 14 without any problems.

Compared to rings, it doesn't rattle, so it's easy to place on the back, and since it's made of denim fabric, you can arrange it with a can badge.

I thought it was much better than the ring!!

Another nice point is that it can be put on and taken off whenever you want.

This is a band that I would like you to try if you are interested in a fall protection ring.

Overwhelmingly comfortable, durable, and detachable!

July 2, 2025

Overwhelmingly comfortable, durable, and detachable! The long-awaited patented smartphone band "Hammo-kun" is here!

Unlike existing smartphone rings and smartphone bands, Hammo-kun does not hurt your fingers or tighten your hands!

The comfort of use was created for the first time by patented technology that structurally separates "1. rubber that connects to the smartphone case" and "2. band to hold the hand".

Durable, flexible silicone rubberAdopted. It is also detachable because it does not use glue to install it on the smartphone case.

You can choose genuine leather OR denim, and I use "genuine leather". Simple design only in black color.

Attach it to the hook with durable thick-walled silicone rubber. It's very easy.

I'm a person who often changes my smartphone case according to my mood, so I used to replace the type that uses glue every time, but I don't need to replace it.

Just pass it through the hole in the cover, secure it with a hook, and put on your smartphone, so you can put it on and take it off without any hassle.

And the fit and stability are very good. You can easily fit four fingers.

I'm a person who looks at my smartphone while sleeping, so sometimes I drop it on my face, and it's very comfortable.

I tried it on various covers, and even if I put it through the charging hole, the cord doesn't come off easily.

The simple design makes it a good gift.

Check it ♪ out

This is the first time I've done this!

"Hammo-kun" is a smartphone band that is easy to ♪ hold, gentle ♪ on your fingers, has an ♪ excellent fit, and does not ♪ feel constricting.

Surprisingly, it can be attached without being glued to the case.

In short, it can be removed freely. (It was easy to put on and take off.) )

The name was given with the aim of being comfortable as if you were rocking in a hammock. It's easy to understand.

And if you put this on, it's really easy to hold your smartphone, which is helpful.

ResistanceLong-lasting thick silicone rubber, handle part (genuine leather OR denim), and high-strength zinc die-cast simple structure

It's safe because it has been proven to be durable.

I chose genuine leather, but denim also looks casual and good.

Even if you buy a new smartphone or smartphone case, you can continue to use it, so I think it's good value for money.

I want ♪ to use it for a long time.
