Standard Postal Boxes are the original solution to cardboard despatch packaging. All of our postal boxes have postage optimised sizing to conform to Royal Mail Postal sizes and keep your postal costs to a minimum. Standard Postal Boxes are designed with easy-fold assembly so tape is only needed to seal the box-lid, double side walls to increase impact protection and strength, and interior flaps to prevent pilfering and theft of items in transit. All of Standard Postal Boxes come in flat packed bundles for easy of handling and minimal storage space. You may also like: ColomPac® Extra Secure Postal Boxes, ColomPac® Module Boxes.
