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. 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.
