A wooden crate used to store and sell bulk items. it would be made with carpentry skill. You would put 100 of the same items into the crate and then seal it much like wrapping a gift. After it is sealed it would average out the ql of all the items just like a bsb and include the items in it's name. ie: Large Crate, Birch wood (pumpkin). after that provided you have the body strength you can pick it up, take it to a merchant and sell it. It could then be opened to get all the goods and the crate would be destroyed.
