These are stuffed animal nose parts. For making animal-type stuffed animals. They are pink triangular noses, and the size is 1.1cm. They are attached by inserting a washer from the back. 12 sets per package. The washers are made of a silicone-like material, so they can be removed. Many noses cannot be removed once attached, but it's good that these can be. If you don't remove them, they stay on securely.
