Use our exclusive space saving storage tube to store your Air-Tite "I" Coin Capsules. Featuring a glued bottom and a red cap, each tube will hold 20 completely closed encapsulated coins. This product is designed to form a vacuum like effect; forcing the air out of the tube from a small hole in the cap, and allowing for a strong seal. It is perfectly normal to push for several seconds as the air escapes. The cap on the tube should fit quite snugly when the air is pushed out if not push or twist a little longer to get the remaining air out. When removing the cap please remember the tube and cap were designed to create a vacuum like seal; slowly pull the cap off and caution against any coin holders falling out.
