Shark teeth in various triangular forms scatter densely across a white ground in continuous linear sketches, creating an all-over pattern with a naturalist's precision. The monochromatic gray linework has an educational quality, as if documenting specimens of varying sizes and angles in an organized, repeating composition. 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.
