We offer Royal PIP boxes designed specifically for their pricing structure. All of these boxes will be considered large letters, so they will not be charged the high shipping rate for small parcels. Sending CDs, books, DVDs, gifts, electronics, games, and so on can be done through these boxes. In the world of packaging, cardboard boxes are becoming the most popular. They serve as an outer protective layer to preserve the products inside. No matter your business type, cardboard boxes are the perfect answer to your packaging needs. Therefore, it increases the demand for the product a step further. All these features have contributed a lot to the success of cardboard packaging.

At Go Packaging Products, our PIP boxes are designed to give your items top-protection during shipment while fully conforming to the Royal Mail large letter (PIP) pricing scheme. Whether you’re sending books, CDs, small electronics, or gift items, the correct PIP box ensures you save on postage and avoid unexpected surcharges.

What Makes Our PIP Boxes Stand Out

  • Royal Mail Approved Sizes — We supply a full range (DL, MINI/C7, C6, C5, C4) in official PIP dimensions. Each box is rated as “Large Letter”, helping you benefit from lower mailing costs.
  • Solid Cardboard Construction — Strong enough to resist bending, crushing or moisture during handling, yet light enough to keep postage costs minimal.
  • Flat-Packed for Efficiency — Stores easily, reduces storage space; customers frequently comment on how practical this is.

Who Our PIP Boxes Are For

  • E-commerce retailers sending dozens of parcels daily who want reliable, compliant packaging
  • Small businesses looking to reduce postage costs
  • Individuals who want to protect media or small, fragile items in transit

Tips to Choose the Right PIP Box

  • Match item dimensions to box size with small allowance for packaging material
  • Choose the minimal size that meets Royal Mail’s large-letter criteria to save money
  • Look for sturdy single-wall board if you’re mailing lighter items; opt for reinforced or heavier board for slightly bulkier or sensitive goods
