Undulating waves in coral red and soft pink cascade across the composition in a mesmerizing rhythmic pattern that appears to pulse and shift before the eye. The overlapping curved forms create an Op-Art inspired optical effect that feels both retro and contemporary, with a cheerful energy that draws the viewer into its hypnotic movement. 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.
