Concentric rectangular lines radiate outward from a central vertical axis, creating a symmetrical pattern that oscillates between advance and recession. The composition is rendered entirely in black ink on white, with thousands of precise parallel lines building an optical illusion of depth and movement that appears to breathe. 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.
