I want you to feel safe using the materials I use, so: ◇ Wire: Stainless steel ◇ Perch: White wood ◇ Beads: Acrylic beads, wood beads, etc. Please refrain from purchasing if you are sensitive to imperfections, as this is a handmade item by an amateur. Please check the detailed sizes in the photos. I hope your beloved bird will enjoy playing with this toy, but some birds may be timid, so please take your time getting them used to it. I make each one with care, so thank you for your understanding. Please feel free to ask any questions. Also, if you purchase multiple items, I will discount 100 yen per item, so please feel free to comment before purchasing. I also sell other bird products. #sorainko
