Detailed description

Unique stackable design

The distinctive triangular design of these postal tubes creates triple thickness board at each end and provides extra protection for your documents. The unique shape means these brown triangular postal boxes pack together and stack without rolling. Manufactured from single wall rigid corrugated board, with a brown Kraft finish, the triangular shape ensures a tough crush resistant postal box that is suitable for posting products or for storage.

Extra-large sizes up to 1100 mm in length make these long postal boxes ideal for industrial plans or blueprints, or for long or cylindrical parts. Quick to assemble and secure, these triangular postal boxes are easily constructed by folding along the pre-creased grooves and sealed with a tough self-adhesive strip, there is no need for glue or tape. Delivered flat packed.
