The suitcase anchor pendant buoy has a rectangular shape with a lay-flat surface. This shape ensures the buoys can be safe storage and transported economically. The inner central steel frame has enough support  branches to ensure the foam core cannot be moved.

The resilient closed-cell polyethylene foam core guarantees self-fendering and is unsinkable even in case of damage. And self-colored polyurethane elastomer skin is resistant to abrasion and ultra violet rays degradation. For the extreme operating environment. The reinforced nylon filament ensures polyurethane elastomer protective coating has higher tear strength.
