Perch Swing Small For Budgies, Java Sparrows, and Small Birds Materials: Hinoki Cypress Wood Stainless Steel Wire 12mm Acrylic Beads Perch: Top Diameter 15mm, Bottom 12mm Width: Top 13.5cm, Bottom 12cm, Height Approximately 15cm This is a non-swinging type of swing. Stainless steel wire is used, so it doesn't swing much. It's designed not to swing much to prevent injury, such as broken wings, when the bird jumps on or flaps its wings. It's made so that birds with weak legs can use it down to the bottom. Screws: Decorative screws, plastic knob Screw part: Iron. Used because it doesn't touch the bird. Washers are stainless steel. 12mm Acrylic Beads Color: See image 2. There are 10 colors, so please comment your preference. I handmade various bird supplies, so feel free to comment. Even just for consultation is fine. All the cut edges of the wood are sanded smooth as much as possible to prevent injury to the small birds' feet and legs, so you can use it with peace of mind. My handmade products are also sold in bird supply stores and animal hospitals. When purchasing, I apologize for the inconvenience, but I will create a dedicated listing for you, so please comment first. Thank you. #Perch #PerchSwing #PerchFoodStand #Budgie #Cockatiel #Lovebird #JavaSparrow #SmallBird #BirdSupplies #SmallAnimal #BirdToy #BirdAthletic
