These are circular wooden pieces cut from scrap wood. A set of 8, in large and small sizes. They are cut but not sanded, so the cut edges are a bit rough. Please use sandpaper or similar to smooth them out. The hole in the center goes all the way through. Material: Pine laminated wood Since it's laminated wood, it's not suitable for chewing toys. How about using them for craft projects? #CircularWood #RoundWood #ToyTires #WoodenTires #CraftMaterials
