A yellow tennis ball caught mid-bounce overlaps a dark navy shadow against a cream ground, framed by four bright green triangular shapes that suggest a grass court viewed from above. The geometric composition uses clean lines and flat color fields to capture the crisp energy of the game in a retro-modernist style. 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.
