No need for comments, direct purchase welcome! I bought this years ago at a rodent event. I think it cost nearly 3000 yen. It's a handmade item by an artist, with a design of a squirrel holding a walnut. It's made of metal, probably pewter. It's solid and heavy, and both the walnut and the squirrel are realistically sculpted. It's about 3.5cm x 2.5cm in size.
