★ Due to budget constraints, I've changed the wooden ring to a hook. This is a hard walnut toy! It's the perfect toy for birds that love hard things! It's bumpy, so it's easy to grip and chew♪ The bumps feel good against their bodies d('∀'*) You can hold it in your hand and play with it, or hang it up. ★ You can customize it as you like by removing the string. I'm sorry that I couldn't lower the price due to the rising cost of walnuts. Thank you for your understanding. m(_ _)m 【Size】Length: Approximately 22cm-23cm Walnut size: Approximately 2cm Uses hemp string
