This tiny clay roller tool

It's like a tiny seam roller. I've seen other seam rollers that are very small width wide, but really chunky in circumference. I'm looking for a little roller tool (not a paint roller) like this that's very very small and thin. The roller part looks plastic here, but if someone finds one in wood or better yet metal (assuming it's not crazy expensive..) that's fine too. Thank you all a bunch ♡
