Cavity Card

The question we get asked most is "what do you do about coins in your slim wallet?" Well, now we have the definitive answer. The Cavity card allows coins, keys and other small items to be carried easily and fuss free in just about any wallet that can fit 4 or more cards. The Cavity Card is perfect companion to a Secrid wallet, and fits in almost any wallet, or can even be used with just two cards and an elastic band, for the ultra-minimalist! 

The slim wallet just found its missing ingredient.
