This is a cushion for a 3COINS bicycle child seat. I purchased it last year (2024) and opened the package, but I have never used it. Photos 3 and later are official photos. Please refer to photo 4 for the size. I think it will be useful in the coming season(^^) Please note that it will be compressed for shipping. I would appreciate it if you could understand that this item is stored at home! #3COINS #3COINS #Cushion #Bicycle #ChildSeat #BicycleCushion #ChildSeatCushion #Black #Baby #Kids #Children #Bicycle #ChildSeat #ColdProtection
