A collage of vintage patent diagrams and mechanical drawings clusters around the word "STRENGTH" in bold serif capitals, featuring weightlifting equipment including dumbbells, kettlebells, barbells, and exercise machines rendered in detailed technical line work. The monochromatic black-and-white composition on a light background conveys industrial precision and functional artwork, evoking early 20th-century patent documentation with its dense arrangement of annotated parts and cross-sections. 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.
