Don't waste your money
These little balls are ping pong balls with Velcro strips clued on.  They stick to any fabric that a piece of Velcro would stick to.  I have actually put a hole in one of my dress shirts when prying the dang thing off my shirt.  I also had the clue not hold and ended up with the strips on my cloths and bald ping pong balls in with my laundry.  Not a single one of them had any hair attached to them.
