It’s plastic. It’s somewhat sturdy. It has the product name EKCO on it, which one can infer means it has something to do in the kitchen. Notice the little dots/points are shaped like a diamond. There are grooves at the top to suggest a finger grip. There is a slit in the middle as if it can slide onto something. I thought it may be a type of pie docker, but if so, why does it have the slit? Any help in identifying this would be appreciated.
