Two detailed scientific sketches of oyster shells rendered in graphite reveal the mollusk's internal and external structure with careful anatomical precision. The warm cream paper grounds these naturalistic drawings, capturing the ridged texture of the shells and their organic, asymmetrical forms through delicate cross-hatching and subtle shading. 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.
