This is a swing for small parakeets, such as budgies, made with binchotan charcoal and colorful beads. The metal parts are made of stainless steel, making them rust-resistant and safe. I bought this for my budgie, but it was too scared to use it, so I'm selling it. The perches are made of binchotan charcoal, which helps to grind down the nails and prevent them from overgrowing. Please refer to the second photo for the size. It's almost unused, but please refrain from purchasing if you are sensitive to items stored at home. Thank you for looking.
