Trying to ship posters, artwork, or important documents without them getting destroyed? These mailing tubes are your solution! You get 2 sturdy tubes in each pack, with actual usable space of 2 inches in diameter and 15 inches long (the tubes themselves are slightly longer to accommodate the end caps). The 3-ply spiral wound construction is seriously durable - they won't bend, flatten, or crease under normal shipping conditions. Both ends come with secure white plastic caps that snap on tightly to keep contents safe and dry. Made from kraft cardboard that's both strong and lightweight, so shipping costs stay reasonable. Perfect for artists shipping prints, architects sending blueprints, students mailing projects, or businesses sending important documents. The tubes are made right here in the USA with quality materials that stand up to rough handling. I've used these to ship artwork across the country multiple times, and everything always arrives in perfect condition. They're also great for storage - keep your valuable posters and prints protected from dust, moisture, and accidental damage. For the price, the quality is outstanding and they're so much better than trying to roll things in cardboard and hoping for the best.
