A stack of concentric eye forms in rainbow hues transitions from warm red at the top through yellow, green, and cyan to deep navy blue at the bottom, each layer outlined in clean lines that create an optical tunnel effect. The geometric precision and color-field progression convey both visual clarity and psychological depth, evoking the sensation of focused perception narrowing toward a single point. 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.
