32 oz. Boston Round Bottles | 3 Pack

Thick walled, Boston Rounds are one of the most classic American bottle shapes dating back to the 1600’s. These bottles have recently had a resurgence in the craft kombucha market due to their fun shape and size.

The leak-proof, threaded poly cone caps are the secret to building an awesome amount of carbonation without a swing top. Each cap has a polyethylene cone inside. With a gentle twist, the lip of the bottle tightens into the malleable plastic cone shape and holds the lip in place, locking in the pressure.
