When you need the absolute smallest card holder, this is the one you'll grab. Designed to tightly hold one card one either side (the back is a mirror image) and an open top space in between for one card or folded note. This will disappear in your suit pocket when you're heading out with the bare minimum credit card and ID.
Turned edges on the card slots, hand stitching and ultra durable yet soft kangaroo leather will make this card holder last a lifetime.
