Set of four 1" special knit balls that are correctly gimmicked for use with a Chop Cup or Combo Cups set. These balls are great replacements for the balls that come with these 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 Combo Cups, Cups and Balls or Chop Cup (not included).
