High end practice golf balls, 42mm diameter, 6 grams.

This is one of the keys to why the MaxPB is such a great tool. These mini (golf ball size) training balls are much smaller than anything you'll hit in a game. So by the time you reach competition, your brain, your nervous system, and your body are already conditioned to handle a hitting task much more difficult than the one in front of you on game day. The MaxPB machine can hold over 100 balls, so to get the most of your practice time, it's a good idea to get at least that many balls.

NOTE: Color mix in "Mixed - Jelly Bean" packs vary pack to pack, just like buying jelly beans, hence the name! Minimum 5 different colors.
