To properly care and protect coins keep them in the best possible condition with Air-Tite Brand Capsules. Air-Tite capsules snap together firmly to form a tight seal, securing your coin for long-term storage. They also keep your coins from coming into contact with your hands. It is best not to touch silver, as the oils from hands can speed up the tarnishing process and leave unwanted fingerprints. Your silver will now be protected, and you will prolong the life of your coins. Capsules are PVC free, archival safe, and are made from an acrylic plastic with a non-yellowing agent. This process results in a product that is hard, crystal clear, and smooth to the touch. Our capsules are securely packaged, un-assembled, within layers of foam to protect them during shipment. The storage tubes feature a glued bottom that will hold 20 completely closed Air-Tite brand coin holders. Tubes are offered with the choice of a cap or plug lid. The cap lid is a tight fit on the outside of the tube and the plug cap is a tight fit on the inside of the tube.
