Nine rings (approximately 30 x 37cm). Recommended for small pet birds such as parakeets and Java sparrows. It's a hanging type, so it can be easily hung in a cage. Made with natural paper. It's non-slip, allowing birds to firmly grip the rings with their feet. Being paper-made, it's especially suitable for indoor use. When using outdoors, please be careful not to get it wet in the rain. No tools are required, and repairs take only a few seconds. A metal clip is attached to the top, allowing you to hang it on cages, ropes, trees, etc. Thank you for viewing. I accidentally ordered two of the same item, so I'm selling one. Please consider this item, understanding that it has been handled by someone else.
