These are our Air-Tite coin holders with colored rings which include navy, green and red. They do not come in as many sizes as our white and black ring Air-Tites, but they are just as popular. Colored rings are available in sizes 38mm-40mm. The Model I-Loop contains a little loop at the top of the holder you can use to make a necklace, ornament or decoration. After you have decided which Air-Tite to purchase, we also have a full line of albums, boxes and tubes designed specifically for our Air-Tite coin holders.
