If you're regularly shipping posters, documents, blueprints, or other items that need protection from bending, these Tape Logic mailing tubes are seriously handy. You get 34 tubes in this pack, each measuring 2.5x20 inches (that's the usable space inside). The kraft paper construction gives them that classic shipping tube look, but don't let the simple appearance fool you - they're made with 3-ply spiral wound construction that provides surprising strength and durability. The white end caps snap securely into place and actually stay put during shipping, which is more than I can say for some cheaper tubes I've tried. They're reusable too, so if you receive something in one, you can easily repurpose it for your own shipping needs. I've used these for sending artwork, important documents, and even as storage for rolled-up posters and maps around the house. They're recyclable as well, which is great for reducing waste. For the price, you're getting reliable protection that won't break the bank. Whether you're a small business owner, artist, or just someone who occasionally needs to ship tube-shaped items, these are a practical solution that gets the job done without complications.
