Swirling bands of deep amber, rust, and chocolate brown form a mesmerizing eye-like vortex at the center of this geologic composition, its curves and striations creating the illusion of depth spiraling inward against a black void. The layered patterns evoke the natural banding found in tiger's eye stone, with warm metallic tones catching light across textured surfaces that suggest both mineral formation and organic movement. 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.
