Screwpop®  Tether makes attaching, removing and carrying your keys made easy.

The Tether™ uses an revolutionary anchoring system.  It’s completely “tool-less” and requires only your hands to fully assemble and/or disassemble.  

Included are four different sized industrial-grade O’rings.  Each O’ring can stretch up to 300 percent it’s original size, and the largest can hold a total of 24 keys (plus bottle opener and keychain attachment).
