Our ZOXLOX Keychain converters are inspired by ingenuity from Zoxers in our own community. In our VIP group, members started posting pictures of clamps that turned their ZOX into keychains. Unfortunately, the clamps were 1-time use and would ruin their ZOX. So, we stepped in to create something amazing.

ZOXLOX are easy to use converters that will turn your ZOX Singles or Straps into the best keychains in the world. All you do is remove the screw, insert your ZOX wristband, and push the screw back in so the wristband is looped over it. Then, screw it back into place and just like that, your ZOX wristband is now a ZOX Keychain. And the best thing about it? You can easily swap your ZOX wristbands in and out to change your keychain any time you feel like it.
