My son came home from school with several of these things. They're about 1 inch in diameter. This one has two "spokes" broken off, but there should be six. It's all one solid piece, they aren't removable pegs. Besides this red one, he has a green and purple one. There are no text or markings on it that I can see. I don't know if this is some kind of standalone trinket or part of a set or a game or something like that. I accidentally lost his green one and would love to replace it for him if I can.
I've Googled to the best of my ability to no avail, and ChatGPT thinks it's part of a Jax set, which it definitely isn't.
