The 3.0 Cubic Foot carton is a favourite in the USA Market, and is becoming a top seller in Canada. Great for bulkier (but not too heavy) items, packing up the kids room, toys, bulky items in the garage. NOT FOR HEAVY ITEMS. It's a large carton, so if your customers pack heavy items they will have a stressful and potentially back-bruising moving day. They won't realize until it's too late that they should have purchased more of the 1.5 or 2.0 cubic foot cartons. Give them great advice, they will appreciate you for it later.
