A black background hosts a detailed white-line illustration of underwater creatures and plants, including jellyfish, octopuses, starfish, shells, and swimming fish arranged in a dense, balanced composition. The scratched, etched quality of the lines creates a contemplative mood that feels both scientifically curious and dreamlike, inviting the eye to discover each creature within the depths. 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.
