Layered bands of deep purple, indigo, and mauve flow across the composition like a natural geode cross-section, with shimmering gold and rose-gold glitter particles scattered along the undulating borders. The effect mimics the crystalline interior of agate, creating luminous striations that suggest both geological formation and ethereal 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.
