A bright yellow tennis ball floats at the center of this geometric composition, its white curved seam catching light against layered circles of gold and shadow. Dark blue triangles point inward from the top and left, while a deep green triangle anchors the lower right, creating a sense of dynamic motion around the still subject on a cream ground. 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.
