Partners Brand MTM236 Triangle Mailing Tubes 2" x 36" White 50 Pack

White Triangle Mailing Tubes

Partners Brand MTM236 tubes are white triangular containers designed for shipping rolled documents, posters or blueprints. The 36 inch length accommodates large-format prints while the triangular profile prevents rolling during transit. Office managers, architects and e-commerce shippers use them to protect wide artwork.

Quick Assembly Flat Design

Each tube ships flat and folds into a rigid triangle without tools or tape. The pre-scored creases lock the edges together in seconds. A common mistake is folding the wrong panel first, which misaligns the closure flaps and leaves a gap at the seam.

Verify Document Length Before Ordering

Confirm that your longest rolled item fits within the 36 inch interior. The bundle contains 50 tubes, so check storage space for the flat-packed supply. No adhesive or end caps are included, so plan for separate seals if your carrier requires them.
