Each capsule tube is designed for storing coins encapsulated in Air-Tite brand coin capsules. Each capsule tube holds up to 15 completely closed coin capsules. Tubes are crystal clear and PVC free with a snug fitting cap. A welded bottom allows for a complete view of any enclosed capsules. Air-Tite coin capsule holders are made from acrylic plastic with a non-yellowing agent, a process that results in a final product that is hard, crystal clear, and smooth to the touch. The cover and base snap together firmly to form a perfect seal enclosing the ring and securing your collectible. Capsules are PVC free, archival safe, and suitable for extended periods of long term coin or bar storage. Coin capsules are securely packaged un-assembled within layers of foam to protect them during shipment. Coin capsules are made in the USA.
