Prevent your shipment from being damaged by package stacking. Place this 3-dimensional cone on top of your shipment to warn those not to stack other packages or pallets onit. The visible alert symbol with 'NO STACK' and 'FRAGILE' warning is printed on all four sides. Secure the fold-up cone with strapping or packaging tape using the slot holes and flanges in the base. Made of cardboard, the cone can be easily crushed if stacked on - proof that your shipment was mishandled.
