We are excited to introduce our very own JP's Corner Brand Self-Locking Tubes. These tubes are fantastic for protecting & storing your coins and feature a new self locking feature not found with similar tubes. They resemble US mint tubes, however with the locking feature there is no need for sticky tape that leaves residue behind. The tube features additive in the plastic before molding to ensure the tube is virtually unbreakable in varying weather and temperatures unlike other tubes on the market. See easy to use instructions below for how it works.
