It's a cute Doraemon tin. It's from the Sanrio collaboration, the I'm Doraemon series. Originally, it contained sweets. I bought it because the tin was cute, but I didn't know what to use it for, so I just kept it stored away. It's clean and doesn't have any rust. I heard you can put a sponge inside, make cuts in it, and use it to store accessories. You could also put cables or medicine in it. Thank you.
