I have a very limited inventory of the kits, once they are gone, they will not be available again. All the kits include easy to follow illustrated instructions and all pre-cut sturdy mat boards. No sewing required. Some of the kits weight between 7 to 11 oz. These are NOT finished boxes, you have to put the boxes together yourself with fabric with the instruction provided in the kits. If you have any questions, please feel free to email me prior to your purchase to avoid misunderstanding and confusion.
