A Portal-themed Keychain, portraying the Weighted Companion Cube!
Who doesn't want to have his/her own Companion Cube...and now to hold your keys together so it will never leave you!
It is handmade from 6-7 oz vegetable tanned leather, then tooled and painted with acryl paint before finishing it off with leather sheen.
It is available in my shop here: [link]
