Our extra heavy duty cardboard boxes are designed and manufactured so they are resistant to high compression forces. This is highly advantageous when shipping heavy items or products you cannot afford to get damaged. These boxes are very popular for those moving house.
Some of our standard cardboard boxes are multi depth. This means the height can be altered to make the boxes smaller, which is useful for saving money on delivery costs or room in your garage. The first three dimensions are Length x Width x Height. Multi depth crease positions are denoted after the forward slash. Buying directly from the manufacturer and cutting out the middle man will save you money as you will be buying at trade prices.
