Interlocking isometric buildings rendered in crisp line work create an endless geometric tessellation across a cool gray ground. The white-lined structures, each topped with diagonal hatching, stack and interweave in three-dimensional perspective, forming a hypnotic pattern that suggests both urban architecture and optical illusion. 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.
