Thank you for viewing! This is a handmade item, so please understand. Perfect for pretend play or display! To ensure children can play safely, we've finished these using only felt, thread, and cotton, without using glue. As these are handmade, there may be slight variations in size, but they are approximately 7cm in diameter. We also offer various strings for an additional 50 yen, so they can be used as educational toys by threading them through the holes. We plan to add more products in the future, so please feel free to let us know if you have any requests!
