RETAINER CASESThese convenient Retainer Cases are designed to hold most retainers, but small enough to fit easily into a pocket or purse. Constructed with durability in mind, the lock- ing mechanism will stand up to heavy use and the hinge is tested repeatedly during manufacturing to ensure strength. A wide hole is provided for use with key chains and other carrying devices. Available in both sparkle and tropical sparkle colors. Dimensions: 1.2" deep x 3.4" wide.
