A detailed line drawing of a Maine Coon cat dominates the composition, rendered in black ink with careful cross-hatching that builds form and texture across its muscular body and luxuriant fur. Handwritten labels point to distinctive features like ear tufts, shaggy pants, and an extensive hair collector, combining scientific diagram conventions with humorous observation in a clean, minimalist style against white ground. Constructed from woven polyester with a soft microfiber lining and a sturdy zipper, made to order for 13 and 15 inch laptops. Everyday protection carrying an independent artist's work, not another plain black sleeve.
