A: One can contains 3 balls and this is what is meant as a 3-pack
A: VERY disappointed that this was only one can even though it is described as a "three pack".
A: NO, IT DOES NOT! I ordered for pick up and they brought me out 10 cans of balls versus what I thought was a 3 can pack. DO NO BUY!
A: There is no mention of high altitude on the packaging.
