This is a set of rolling mats from Kai Corporation. You can make flower-shaped and star-shaped rolled sushi. I received it from a relative. I've kept it for years, hoping to make cute sushi if I could master it, but I never used it. Since I don't expect to use it in the future, I hope someone else can. The size is as shown in the photos.
