The secret is the colored layer of non-toxic freezer gel between the exterior and interior wall. By placing the mugs into your freezer for about two hours (they work best when placed upside-down) the gel freezes, offering you a unique way to keep your beverage icy cold w/o ice! Your drink won’t get watered down as one with ice would.
