Repeating semicircular forms radiate outward in dense, symmetrical rows, their surfaces filled with fine linear hatching that creates depth and movement across the composition. The pattern alternates between dark and light tones, producing a mesmerizing optical effect that suggests both natural phenomena and geometric precision. 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.
