Stack-able and durable trays are made of "low density Poly" similar to your cutting board at home and fill about the same footprint. This makes the Gold Cube very compact yet tough and ready for any situation you can throw at it. Everything on the Gold Cube is ready for action..Simply set it up, hook up the 12 volt pump and you're ready to go! You can pump from a creek or recycle from a tub.
