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 uses solid, one team lines, whether you play with 2 or 3 players per team. Simple.
6 chrome plated steel boules, in a red zippered case + 1 red & 1 green wooden target ball + 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. NOT International as the total weight exceeds 20 lbs (9 kg).
In case you want another design, besides the solid and double circles in the 6-set.
Single wide lines come in a blue case. Single narrow lines in a green case.
