Boxtopia is committed to delivering your boxes as quickly as possible. It usually takes just a few days to make boxes from our stock board although, subject to workload, we can often supply products on a next day delivery if necessary. For larger quantities of boxes, it is more cost effective for us to buy the board in cut to size so that we can make the boxes without any waste material. Typically, we can despatch these within a week. If you have a deadline, just check with us first.
