Undulating vertical waves in bright kelly green and soft blue alternate across the composition in a mesmerizing repeating pattern that evokes the fluid, organic aesthetic of 1970s artwork. The rhythmic curves create a sense of movement and flow, with each wave mirroring its neighbor to produce a hypnotic, meditative effect. 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.
