■ A new product that solves the dissatisfaction with conventional smartphone bands and smartphone rings
In recent years, there has been an increase in finger problems such as smartphone tendonitis due to prolonged use of smartphones, and the demand for smartphone bands that reduce the burden on the body is increasing.
However, conventional products lack flexibility, or even if they are flexible, they are too tight and put a heavy burden on the fingers, making it difficult to use them for a long time. In addition, many of them lacked durability due to the heavy load on the moving parts, and it was troublesome to hide the adhesive marks when replacing them.
Therefore, the smartphone band "Hammock-kun" to be released this time is " (1) Airy and comfortable to use (2) High durability (3) No need to glue to the case & removable It was developed as a product with such characteristics. It is a freedom band that eliminates the pain of the hand holding the smartphone and the anxiety of dropping the smartphone.
The first is a black color, and we will sell "Hammock-kun" in two types of fabrics, genuine leather and denim.
■ Features of Hammock-kun

(1) Airy and comfortable to use
By separating the silicone rubber part that attaches to the smartphone case and the band part of the handle, it has moderate elasticity but does not feel tight, and it feels as if it is wrapped in a hammock (this comfort and product shape are the origin of "hammock'n"). In addition, the two O-rings that connect the elastic band and the leather band can be moved from side to side, making it a comfortable fit in either left or right hand.

(2) High durability
Since it is an item that is used every day, we were particular about its durability.
We have conducted multiple durability tests, including 10,000 tensile tests conducted by a third-party organization*2, to prove that it has excellent durability.

(3) No need to glue to the case > Removable
It uses the camera hole and cable hole of the smartphone case and fixes it with a silicone band, so there is no need to use adhesive on the case. In addition, the "Hammock-kun" can be easily put on and taken off according to business and private scenes. Even if you buy a new phone case, you can continue to use it as long as it fits the size, and it is not disposable.
Other:
● Patented : The highly durable structure that does not hurt your hands even if you use it for a long time has been patented (Patent No. 7351074).
● Wireless charging By sandwiching the wireless charger between the silicone rubber and the case, it also supports wireless charging.
● Compatible with "Push Activity" : The denim version can be attached with a can badge to support "push activity".
■Future development
・Size variations
This time, the L size (the distance from the camera hole to the cable hole is 115 ~ 140 mm) will be released as the first step, and we plan to develop variations such as M size in the future.
・Design variations
We plan to add new lineups from time to time, such as genuine leather with studs with a rock taste.
・B2B expansion
Since it is possible to print on the hand-held band part of "Hammock-kun", it can be developed as an anime character, fan goods of sports teams and musicians, and corporate novelties.
・Overseas expansion
We have already applied for an international patent (international application number: PCT/JP2024/020676), and we aim to acquire sales partners in each country and expand into overseas markets.
