Sixteen colorful sea slugs arranged in a 4x4 grid float across a soft pink background, each creature rendered in bright pastels with distinct patterns, spots, and color combinations. The playful illustration style emphasizes rounded forms and cheerful hues, creating a whimsical underwater collection that feels both scientifically inspired and purely imaginative. 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.
