This is Puff Bub. Not much going on inside BUT you can change that by adding a yarn ball! A yarn ball about 4.5" in diameter would be the recommended max size. 4.5" looks best for display while 4.25" spools a lot easier. - Size: 6"x6"x3" Weight: 1lb 5.3oz - Please do not place Puff Bub in the dishwasher as he has delicate parts that would prefer not to impacted by water jets and metal racks! Hand-wash with soap and warm water would be best. As this is a handmade artwork, by purchasing this piece, you understand that each piece will vary slightly but will be very similar to the product photo. I hope that you will love your piece in it's uniqueness.
