I am pretty sure some one has asked this before, but how long does balls stay hard in unopened cans? I am just wondering because I donno if I should just use them all now since they might go dead in like a year or so. Thanks for any help in advance.
If the cans are not open they will last more than a year... store them at warmer or room temperature... I have a case, has been there for few months already... I would say it will be good for at least 2 years, until the pressure leaks
