Set of four 1" knit balls, ungimmicked, for use with a Cups and Balls set. These balls are great replacements for the balls that come with the Cups. Keep a spare set in case you lose one of the originals, or in case the original balls become worn or dirty.
 
This is a set of four balls only. No instructions come with this set. Use with your own set of Cups and Balls (not included).
