A checkerboard pattern of black and white squares warps and undulates across the composition, creating the illusion of a curved, three-dimensional surface that seems to breathe and shift. The geometric precision of the grid contrasts with the fluid distortion, producing a hypnotic optical effect that draws the eye inward. 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.
