20-foot shipping container made from corrosion-resistant Corten steel. It has double doors at one end with a secure closure, a wood or bamboo floor and ventilation openings to prevent condensation. Being a used container, its condition may vary: Cargo Worthy (CW) fit for transport, Weather-Tight (WWT) with a guarantee of air- and water-tightness, or sold as-is with possible repairs to be expected, which may show visible signs of wear (scratches, dents, light corrosion) and previous repairs to the floor, doors or panels.
