KINTO BONBO Soup Mug 200ml Set of two: Orange and Blue Gray Made of plastic Dishwasher safe Purchased on Amazon this year for 935 yen each. The colors are very cute and stylish. Used about 10 times each. They were too small for elementary school students, so I think they're suitable for babies up to around 5 years old. There are no noticeable scratches or stains, but if you look closely at the inside, there are many fine scratches from spoons, although they don't show up in the photos. The shape is not perfectly round, and it seems slightly distorted. Please check the photos. Please purchase only if you understand that these are used items. Thank you.
