VEVOR - Aluminum Hand Truck, 2 in 1, 300 lbs Load Capacity, Heavy Duty Industrial Convertible Folding Hand Truck and Dolly - Black

This folding hand truck is built from fortified aluminum and carbon steel. It's corrosion-resistant and rust-proof. As we said, it transforms from a 2-wheel hand truck to a 4-wheel platform truck in seconds. Those solid rubber wheels come off easily, so you can store it without hogging space.
