To keep life simple, all sets come with 3 solid boules, and 3 with circles. Easy to tell apart.
If you buy 2 sets, one team used solid, one team lines, whether you play with 2 or 3 players per team. Simple.
6 chrome plated steel boules, in a zippered case + 2 red wooden target balls + a measuring string. Boules are approx. 73 mm, approx 720 grams.
The chrome will wear off over time, but that does not affect play.
Note: some stores sell 6-sets with 3 pairs of 2 boules. That doesn't work well ...
Two sets fit in a Flat Rate Priority Mail carton at $13.60 within the 50 states.
