About

SPRASANN LLC is a Tokyo-based company behind “Hammock’n,” a patented non-adhesive smartphone band that slides between a phone and its case. Our soft, cushioned “hammock-like” strap supports the fingers, improves one-handed grip, and helps reduce discomfort and fatigue from long smartphone use.

Hammock’n is available in leather, denim and rock-style studded designs, and comes in multiple sizes to fit a wide range of phones and cases. The band can be attached and removed without tools or adhesive, so users can switch cases freely without damage or sticky residue.

We aim to provide a simple, elegant solution for people whose hands get tired or sore from holding their phones for work, gaming, social media, or video streaming. SPRASANN LLC is also exploring collaborations with case makers, designers, and brands to create original phone cases paired with Hammock’n bands for global customers.
