Fifteen numbered billiard balls in jewel tones and earth hues sit against a black background, arranged in a 4x4 grid with one blank tan sphere in the lower right corner. The worn, textured surfaces of each ball give the composition a vintage poolroom authenticity, while the precise geometric layout and cream-colored numerals create a sense of orderly calm. 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.
