A technical patent illustration for toilet paper unfolds across a dark chalkboard ground, rendered in white line work with the precision of a 19th-century engineering schematic. The composition presents multiple views of the rolled paper and its mechanism, marked with figure numbers and flanked by inventor signatures, capturing the mundane with the gravitas of industrial innovation. 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.
