Thank you for viewing! ஐ This is a rope swing made from natural white birch branches from Hokkaido. The perches are handmade one by one ஐ The arch part is made of stainless steel wire and cotton rope. Stainless steel wire is inserted into the core of the rope, but it is a soft shape, so you can deform the arch part (e.g., image 3). Note: If you have birds larger than button parakeets or cockatiels, there is a risk of them biting and breaking the beads, so please be careful. Regarding use, please make your own judgment as the owner m(_ _)m * Button parakeets are not included.
