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 is not included. The nest 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 is random. Desired colors will be an additional 50 yen. Since it is handmade, there may be some individual differences. If you are concerned about minor details, please refrain from purchasing. m(_ _)m I hope your beloved bird can enjoy spending time with you. ☆*:.。. o(≧▽≦)o .。.:*☆
