A fossilized ammonite spiral dominates this close-up composition, its pale grey-blue shell contrasting sharply against surrounding darker brown and rust-toned specimens. The layered, chambered geometry of the central shell echoes outward in concentric patterns, creating a mesmerizing sense of depth and natural mathematical precision. 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.
