Three scientifically rendered butterflies are arranged vertically against a warm beige ground, each species rendered with precise detail and naturalistic coloring. The composition moves from a delicate blue Common Blue at top, through a striking Marbled White with bold black markings in the center, to a soft brown Meadow Brown at the base, evoking the observational tradition of natural history illustration. 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.
