These are beautiful. I’ve ordered three sets.

Rainbow Two-Toned Tumblers (set of 6) Preorder, ship in 3-4 weeks

I ordered these as a housewarming gift for a friend after seeing them online. They're absolutely perfect and super cheerful. Overall, I really love the colors, size, and weight of the cups--I actually also ordered some of the strata tumblers for myself and have been really pleased with the quality and designs on both sets. The items came quickly even as a pre-order and were packed really nicely for shipping.
