Dark brown and black organic shapes float and cluster across a warm cream ground, creating an abstract interpretation of tortoiseshell patterning. The composition balances scattered larger forms with smaller specks, evoking the natural marbling found in animal shells while maintaining a fluid, almost liquid quality. 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.
