The Escuyer leather card sleeve is the thinnest piece in the range — a single open sleeve of Italian full-grain vegetable tanned leather with no card slots or internal structure. Cards and folded bills slide in from the top. As the leather softens with use, the top edges curl inward naturally to keep contents in place. It holds up to 8 cards and sits flat in a pocket.

Available in four hand-dyed camouflage patterns at €55: military, orange, blue, and light green. Each colour is applied by hand in layers at the Tuscan tannery, which is a certified member of the Genuine Italian Vegetable Tanned Leather Consortium. No two pieces come out exactly the same. Handmade in Portugal with hand-painted edges in organic paint and a gold Escuyer logo.
