The only real difference between a Cargo Worthy (CWO) and Wind and Water Tight (WWT) container is whether it can pass a CSC Survey and be safely placed at the bottom of a stack of seven (7) loaded containers for shipment on a cargo ship. Both CWO and WWT are going to look similar: surface rust, dings and dents, etc. Whether the used shipping container you purchase is WWT or CWO, it is going to look like a used metal shipping container. WWT boxes are more likely to have cosmetic issues simply due to their age, but all WWT containers can be repaired to CWO status. With either option, we guarantee that your shipping container won't leak, will have doors that seal, and floors free of holes. If you're worried about how it looks, pressure washing and painting used containers goes a long way. One Trip containers are Cargo-Worthy containers that were manufactured within the last 1-2 calendar years and generally have little to no cosmetic issues (maybe a few dings/dents and scraped paint from being stacked, but that's it).
