Diameter: 4cm Macaron coin case with a ball chain. The color may appear different from the actual product depending on your device. Discounts on single items are not possible. *If using the bundle feature, please do not change the price. The price will be adjusted after approval. *Requests for discounts to a desired price will be declined. Keychains can be added for an additional 50 yen. Please comment before purchasing so I can adjust the price. *Please note that if you purchase immediately, you cannot change it to a keychain. It can hold about 4 x 500-yen coins. It's convenient for storing medicine, rings, chain necklaces, and other items that are easily lost. It can hold 5-6 x 10-yen coins, so you could put it on a child's bag and use it for emergency phone calls. I make each item carefully, but there may be imperfections such as shape distortions and uneven stitches. Please understand that this is a handmade item and purchase accordingly. #KurumiNoBaba #MacaronPouch #Keychain #MedicineCase
