A grid of vertical book spines in warm oranges, deep browns, soft blues, and hot pinks creates an orderly yet playful composition that evokes a mid-century bookshelf. The stacked rectangular forms, punctuated by white dividing lines, establish a rhythmic pattern that balances geometric precision with the organic variety of color blocking. 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.
