I made a flat, round pouch. It's perfect for small items like candies or medicine. With the scorching heat this year, you can hang it on your bag for easy access to things like salt candies. If you don't need the key ring, you can remove it. This is a handmade item, so there may be some imperfections like uneven stitching. I would appreciate it if you would consider this before purchasing. The diameter is approximately 13 cm. Made with 100% cotton fabric. Uses a 12 cm zipper. Uses sashiko thread from Yuzawaya. Includes a D-ring and a key ring. Pre-washed and ironed.
