Large size (13.5cm diameter) Two strings are attached to hang it like a nest. This is handmade. I think it's good for small birds such as chicks, young birds, society finches, Bengalese finches, and Java sparrows. The nest lining is not included. Nest lining can be sold separately. It will be an additional 200 yen. If you wish, please comment and I will change it. The color of the nest lining is random. Desired colors will be an additional 50 yen. *White is not available. Since it is handmade, there may be some individual differences. If you are concerned about minor details, please refrain from purchasing. m(_ _)m May your beloved bird have a fun time with its owner. ☆*:.。. o(≧▽≦)o .。.:*☆
