SPRASANN LLC has launched Hammock'n, a Japanese-designed, non-adhesive smartphone band that supports the fingers like a soft hammock. The strap aims to reduce hand and little-finger strain during long phone use while helping prevent drops.
TOKYO, Japan - illiNews -- SPRASANN LLC today announced the international launch of Hammock'n, a patented smartphone band developed in Japan to help reduce hand and finger strain during everyday phone use. The company has opened an English-language global site and online store to serve customers worldwide.
In user research conducted in Japan, 89.6% of regular smartphone users reported feeling pain, fatigue, or discomfort in their hands during daily use (n=500). Based on these findings, SPRASANN identified hand fatigue from prolonged smartphone use as a widespread issue and set out to create a solution that supports the device while relaxing the grip.
Hammock'n is a hand strap that is installed between the smartphone and its case. The component that anchors the strap to the case is separated from the soft band where the fingers rest, allowing the load to be distributed across a wider area—similar to how a hammock supports the body. This design aims to keep the phone secure while reducing pressure on the fingers, even during long sessions.

Instead of adhesive tape, Hammock'n uses a non-adhesive structure that takes advantage of the camera opening and charging port of the phone case. This enables users to attach and remove the band without leaving sticky residue and to reuse it on other compatible cases. The structure is protected by a Japanese patent (Patent No. 7351074), and patent applications are pending in the United States, China, and Europe.
The product line includes genuine leather models suitable for business use, denim models for casual everyday wear, and a studded "Hammock'n Rock" version designed with music and street culture in mind. Additional colors and designs are planned as the brand expands internationally.
To support global customers, SPRASANN has implemented an e-commerce system on its official website. Visitors can review product information, design variations, and size details before purchasing Hammock'n directly online.

SPRASANN is also seeking distributors, retailers, and collaboration partners in regions where smartphone use is widespread and hand fatigue is a concern. Potential partners include smartphone accessory shops, electronics retailers, online stores, music-related stores, live-venue merch booths, motorcycle shops, and street-culture select stores.
