Overlapping concentric arcs in cyan and navy create a mesmerizing wave pattern inspired by the traditional Japanese seigaiha motif, suggesting endless ripples across deep water. The geometric repetition builds a rhythmic, almost hypnotic composition that balances mathematical precision with the organic flow of ocean 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.
