This is a bird call that I purchased at Ghibli Park quite some time ago. I found it in storage while decluttering my home. Due to long-term storage, the tape on the product description has become discolored, likely from the strap, turning yellow in the adhesive areas. The wooden part of the acorn may be a bit rough due to its natural material, and the metal part that you turn may be faded. It still makes a sound. I have never untied the strap since I bought it. I have uploaded photos, but if you would like to know more about the specific condition, please comment before purchasing.
