For this set of four shot glasses, we take advantage of the same physical principles that make our Whisky Stones so effective at chilling - we just do it in reverse, cooling from the outside in, rather than from the inside out. As always, soapstone is non-porous and will not trap flavor or odor from one use to the next. Store in the freezer for a super-cold shot or out in the open for simply a super-cool look.
