★ Aomori Hiba wood and cork! The stainless steel wire is doubled for durability, and twisted tightly so it won't spin around. It's stable! When hanging, please adjust it slightly yourself. For safety, the top part is wrapped with hemp twine and secured with a cable tie. The bottom is designed for playing by pulling. Paper yarn seems to be a favorite lately, so I used paper yarn! It's intentionally cut roughly to make it easier to rub their beaks. (σ゜Д゜)σ They can sharpen their long beaks with this! Length: Approximately 18cm-20cm Width: Approximately 4cm-5cm
