An abalone shell opens in layered, iridescent detail, its interior surface catching light in shifting greens, purples, and golds across a luminous lavender ground. The composition builds through translucent washes and linear marks, creating depth and movement that echoes the shell's natural spiraling architecture. 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.
