Intricate technical drawings of vintage optometry equipment fill a black ground, with the central phoropter flanked by an array of lenses, frames, and diagnostic instruments rendered in fine white line work. The composition evokes a patent diagram, dense with mechanical detail and labeled with period typography that reads "OPTOMETRY" across the top. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
