Golden and bronze moths and butterflies are arranged in a symmetrical grid against a deep black ground, rendered in the meticulous style of 19th-century natural history illustration. Each specimen is depicted with intricate detail and metallic warmth, creating a sense of scientific wonder and timeless elegance through their precise positioning and jewel-toned coloring. 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.
