Compared to the standard Card Clip, it protects cards from all sides; cards do not fall off and do not get damage under the pressure of a metal. The Cardistry Bag is made of quality Cordura-like material that protects cards not only from scratches and fall, but from water (inside is a waterproof protective layer) as well. Your favorite cards will stay dry even in unexpected rain and protected from coffee spills. The Cardistry Bag opens with a zip.
