A bright yellow tennis ball floats at the center of a geometric composition divided by cream and tan diagonal stripes, with a dark teal triangle anchoring the upper left and a forest green triangle grounding the lower right. Soft shadows fall across the ball and background, creating subtle depth within this minimalist, color-blocked arrangement that captures the essence of the sport through pure form and restrained palette. 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.
