Protect and ship long items with ease using our 435mm Postal Tube Box with Peel & Seal closure. Designed for strength, convenience, and professional presentation, this durable cardboard tube box is perfect for safely mailing posters, artwork, documents, prints, and other long products.

Made from strong corrugated cardboard, the box provides reliable protection against bending and crushing during transit. The square tube design offers practical benefits compared to traditional round mailing tubes, as it prevents rolling, stacks neatly, and is easier to store and handle in packing environments.

The built-in peel & seal adhesive strip allows for quick and secure closure without the need for additional tape. Simply remove the backing strip and press the flap down to seal, making packing faster and more efficient for busy packing operations.

With internal dimensions of 435mm x 110mm x 110mm, this postal tube box is ideal for businesses that regularly ship longer items while maintaining a clean and professional packaging solution.
