When you are looking to purchase a Sea-can, perhaps the first thing to think about is buying a new or a used one. As you may know, sea-cans come in a variety of sizes. However, used sea-cans also offer various options when it comes to condition of the unit. Below, we are going to talk about the different conditions of used sea-cans and the terminology associated with them.
