Thank you for viewing! Size: Approximately 10.5 x 7.0 (cm) Thickness: Approximately 5 (mm) Color: Pink This is a simple, hand-stitched card case made of cowhide leather. Inside, there are pockets on both the left and right sides (each can hold about 3 cards) and a key ring. It's designed to fit easily into small bags and pockets, making it very convenient. I hope you'll enjoy the feeling of it becoming familiar to your hand as you use it. This is a handmade item. I create it carefully from cutting, but since I am an amateur, the techniques in the details are not perfect, so please consider purchasing with the understanding that.
