Two horseshoe crabs rendered in detailed stippled ink occupy a cream ground, their shells articulated with careful cross-hatching that reveals the creatures' segmented anatomy and spiny undersides. The composition balances the creatures vertically, with one positioned upright and the other inverted, creating a naturalistic study that suggests scientific observation paired with careful draftsmanship. 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.
