A bright yellow tennis ball floats at the center of a geometric composition divided by sharp diagonal bands of deep blue, cream, and sage green. White curved lines trace the ball's characteristic seams, while overlapping circular shadows in navy and olive suggest movement and dimension against the angular color-blocked background. 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.
