Square Mailing Tubes 5x5x18

These square mailing tubes measure 5 by 5 by 18 inches and arrive in a bundle of 25. They are designed for shipping rolled documents, posters or blueprints that must stay flat and protected. The white exterior provides a clean surface for labels and postage marks. Partners Brand supplies them as standard shipping and mailroom stock.

Easy assembly and common issues

Each tube ships flat and folds into a rigid square shape without tools or adhesives. The self-locking tabs hold the corners securely once pressed into place. Mis-folded tabs are the most frequent cause of a loose end cap during transit. Over-packing the tube can stress the seams and lead to splitting at the corners.

Suitable uses and limits

The 25-count bundle suits offices, print shops or artists who mail flat artwork on a regular basis. Buyers who need longer tubes for oversized plans or heavier-duty walls for fragile items should look at other options. The fixed 18-inch length limits what can be shipped without cutting or rolling tighter. Single-unit purchasers may find the bundle quantity excessive for occasional use.

Questions about this item

How can I confirm the tubes are the correct 5x5x18 size after opening the bundle?

Measure each tube; the square cross-section should read five inches by five inches and the length eighteen inches.

What comes in the box and do I need to buy caps separately?

The bundle contains twenty-five square white mailing tubes; end caps are not included and must be purchased separately.

Should I choose the M5518 bundle of twenty-five or a different quantity?

The M5518 is sold only as a twenty-five-count bundle; if you need fewer tubes you would have to open the bundle and store the rest.
