Extra large size (15cm diameter) Two strings are attached to hang it like a nest. This is handmade. I think it's good for small birds like chicks, young birds, Java sparrows, Bengalese finches, and zebra finches, as well as for medium-sized parakeets. The nest is not included. The nest can be sold separately. It will be an additional 200 yen. If you wish, I will change it if you comment. 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 birds can enjoy spending time with their owners. ☆*:.。. o(≧▽≦)o .。.:*☆
