The Cavity Tray is slightly thicker than a standard debit or credit card yet opens up a world of possibilities for your Ridge wallet. It allows you to carry a few coins, keys, and other small items in your Ridge wallet while maintaining a slim profile.
Installing the Cavity Tray is as simple as it gets.
Place the Cavity Tray on a flat surface, ensuring the side with the logo and the "Aluminum" text is up.
Put your desired items (coins, keys, etc.) on the tray. Avoid stacking items above the level of the tray and overfilling it.
Once filled, line the Cavity Tray's longer side with the Ridge wallet's opening.
If necessary, slightly spread the Ridge wallet apart.
