Planet Friendly Stackable Legal Desk Tray Made with 85% plant-based materials instead of petroleum. Imagine that! Contains no BPAs, phthalates or other nasty chemicals. Seriously durable and oh-so fashionable in 4 delectable colors. Non-slip rubber feet keep it in place during desk-clearing temper tantrums. Trays sold individually, so buy multiple trays to stack. Stacking posts sold separately.
