Plastic is convenient to produce, though not the most durable stuff in the world. To get around this, San-Francisco-based industrial designer Mark Kelley created a line of desktop organizers made from polystone.
Polystone--a blend of polyurethane resin and powdered stone--is more substantial than plastic, featuring a smooth, almost porcelain-like finish, yet is lighter than stone (not to mention easier to work).
Produced under Kelley and partner Richard Liu's BASE brand, the clean-looking, minimalist line currently consists of three (really, four) products: Object 001, a desk cup; Object 002, a tall desk cup; and the combination Object 003, a small cup that nests in a tray. Check 'em all out here.
