This is a hand-stitched genuine leather card case made with gold genuine patent leather and black cowhide, similar to the leather used by Chrome Hearts and Margiela. The stitching is black. We use high-quality, durable Japanese thread, also used in the interiors of cars and airplanes. It is elegant and simple, yet makes a statement. From pattern design to leather cutting, hand-stitching, and edge (side) and flesh side (back) finishing, everything is done by one person over time. Manufacturers call this "bench-made," and while inefficient, it results in a higher price. It is also highly durable. [Size] Width: 10.0 cm Height: 6.5 cm To enhance its appearance and ensure longevity, the edges (cut surfaces) and flesh sides are meticulously finished. Simple yet impactful. We use leather with a substantial thickness to avoid a cheap look. It features a single pocket, a practical design. Ideal for IC commuter passes, point cards, credit cards, and IC cards. Something you don't see often. Simple yet impactful. "I wish I had something like this." This is the concept behind its creation. While it appears simple, significant attention has been paid to its shape. Essentially, each item is one-of-a-kind, and we use quite rare leathers. Many items cannot be reproduced, so please consider purchasing early if you are interested. We can create similar items if the leather is available, but we do not accept orders from non-repeat customers. It will be packaged in a new envelope. Perfect for gifts. This is a handmade item. Please refrain from purchasing if you expect manufacturer-level quality or are overly sensitive. We will ship promptly via standard mail.
