Purple and blue seashells radiate outward in overlapping layers across a soft white ground, their ridged surfaces rendered in delicate watercolor washes. The composition creates a rhythmic, tessellating pattern that feels both organic and meditative, with each shell's striations catching light in subtle variations of lavender and periwinkle. 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.
