A hammerhead shark glides through dark water in stark monochromatic tones, its distinctive flattened head and extended pectoral fins rendered in precise detail against a black void. The composition captures the creature mid-swim from a frontal angle, emphasizing the alien geometry of its form with silvery highlights that suggest both the creature's metallic skin and the mysterious depths it inhabits. 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.
