This uniquely designed Letter/Legal size (15" x 12" x 10") file box is easily built in one simple step.  No panels to fold or tabs to lock.

Unprecedented strength.  Constructed of 200# corrugated and double wall on all 4 sides and the bottom.  This tremendous strength allows the file box to be stacked without crushing.

The sturdy tight fitting lid, made of the same 200# corrugated, stays firmly on the box and keeps documents where they belong.

These boxes are also great for storing items other than just files (desk items, literature, samples, etc).  They are also the perfect size to be used as moving boxes (the handles are built right in).

Sold in bundles of 10.  Shipped flat to save on storage space.
