Thank you for viewing. The cat I was looking after has returned to its original owner, so this item is no longer needed and I am selling it. - Product Name: Pet Interactive Ball Exercise - Material: Natural Bamboo - Size: 21 cm diameter x 10.8 cm height - Included: 9 wooden balls (without bells), hex wrench, instruction manual Although a wrench is included, it can be easily disassembled and assembled without using it. There are small dents due to the natural material. The dark spot on the top was present from the time of purchase. There are small scratches, but it hasn't been used much, so the condition is good. For those who understand that this is a used item. Please refrain from price negotiations. Thank you very much.
