A bright yellow tennis ball floats across a geometric composition of sage green and cream triangles, its curved white seams catching light against layered color blocks. The minimalist mid-century style creates a sense of motion and play, with the ball appearing to move diagonally across the carefully divided court-inspired 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.
