Description

White C4 PIP Large Letter Box 349 x 249 x 24 mm – a slim, white cardboard mailer designed around popular large-letter style dimensions (always confirm with your carrier). Perfect for A4-sized documents and flat products.

Internal size: 349 x 249 x 24 mm. Supplied in packs of 25.

Uses & Applications

  • A4 documents, catalogues and brochures.
  • Flat books, magazines and notebooks.
  • Thin clothing, T-shirts or textiles folded flat.
  • Prints, artwork, calendars and marketing packs.

Suitable For

  • Flat, light items that must stay rigid in transit.
  • Businesses aiming to benefit from large-letter style postal tariffs where applicable.
  • Brands wanting a neat white surface for stickers, branding and addressing.

Recommended Tape

  • Most PIP mailers use integral locking tabs; tape may be optional for very light items.
  • For added security, use a strip of 25–48 mm clear or white tape along the main opening edge.
  • Branded labels can also act as a tamper-evident seal.

Recommended Void Fill

  • Flat tissue or paper sheets to protect printed materials.
  • Card or board stiffeners for extra rigidity when mailing artwork or photos.
  • Thin foam or bubble wrap for books or small electronics.

How to Use

Pre-crease and fold along the lines, insert the documents or product flat, then add protective sheets above and below if required. Close the tuck-in flaps securely and seal with tape or a label for extra protection in the postal network.

FAQs

  • Q: Will this always be accepted as a large letter?
    A: It’s designed around C4 large-letter style sizing, but carriers set their own thickness and weight rules. Always check the latest size and weight requirements.
  • Q: Is it better than a padded envelope?
    A: For items that must stay flat and rigid, a card mailer offers significantly better protection than a soft envelope.
