【Product Description】 Thank you for viewing! This card case was made by my 7-year-old son, who is passionate about leathercraft, using a home sewing machine. The front is made of soft "pig suede," and the inside (back) is made of "vegetable-tanned cowhide." • Materials: Vegetable-tanned cowhide & Pig suede (Enjoy the texture of genuine leather) • Design: A hole is made in the center, making it easy to push out cards with your finger. • Uses: For transportation IC cards (Suica/PASMO, etc.) or frequently used point cards. • It is sized to fit standard credit cards and IC cards. • Please confirm before purchasing This is a work made with great effort by a child. There may be some unevenness in the stitching and small scratches from the manufacturing process, but we hope that those who appreciate the handmade quality will purchase it. The proceeds will be used for the cost of materials (leather) for my son's next creations. Thank you for your support!
