Doggyman Cotton Ball M Set of 3

A ball woven from cotton rope without using glue. I can't find the beginning or end of the knot. So it's not easy to solve. A dental care toy that massages the gums while chewing on the tightly woven cotton rope to remove stains from the teeth. Just like a ball, you can roll it around and play with it. It can be washed with water and can be used cleanly for a long time.
