Square Mailing Tubes for Document Shipping

These white square tubes measure 5 by 5 by 12 inches and come in a bundle of 25. They are designed for shipping rolled documents, posters, or blueprints without folding. The square profile prevents rolling during transit and stacks neatly on shelves.

Replaces Round Tubes When Stacking Matters

Round tubes waste space between curves and tend to roll off conveyors or shelves. These square tubes fill rectangular boxes completely and stay put on flat surfaces. The upgrade is worth it when you ship volume regularly and need pallets or cartons to cube out efficiently.

Suits Offices and Print Shops With Regular Mailings

Ideal for businesses that mail architectural plans, artwork, or certificates in consistent quantities. The 25-count bundle matches typical monthly runs. Not suited for buyers who need adjustable-length tubes, heavy-duty crush resistance, or single-unit purchases for occasional use.
