Layered blue and gray oyster shells stack vertically across a deep navy sky scattered with stars and a crescent moon, surrounded by delicate aquatic flora and small swimming creatures in shades of teal and cyan. The intricate linework and watercolor-like application create an ethereal, dreamlike quality that merges the oceanic with the celestial. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
