Great Product
These are great quality drawing tube boxes. The Post Office formerly supplied them, but no longer. 24" rolled drawings fit great and are very sturdy for sending to clients. The "lay-flat" storage is a HIT! since I need to store 20 or 30 at a time!

Works as intended
Good quality and worked well for organizing and storing some of my common cards until I had enough to sell as bulk.

Holds the blueprints for storage
Good Valur for the price. Tabs are a little difficult but works

Protects my fragile product
The boxes are medium/light weight. I do ship fragile items, and pad them well so if the box does get damaged, there is little chance the "fragile" item I am shipping will suffer. Most of the time I only use 1/2 of the box (about 12") which makes a stiffer package, and I am liberal with the packing tape. I have shipped approximately 80 packages with this product by USPS Ground Advantage and had no failures.

Years of use, keep coming back to these
I run a business and this is my most common size needed for shipped items. These boxes are economical and easy to assemble, and have been consistently good every order I’ve had of them in the past 5 years since I first tried them.

Great Wrapping = Perfect Boxes!
Arrived very well wrapped and the boxes look great nothing bent or broken off.

Weak Cardboard Tabs
I bought these Aviditi long cardboard boxes as an alternative to mailing tubes for posters. I am disappointed in the quality of the cardboard. The tabs are weak and the layers separate when building the box. I only use these boxes for cheap items and will not buy them again.
