Heritage® Clamshell Boxes are the finest archival storage boxes on the market and constructed from our exclusive E-flute Heritage® Corrugated Board. It's strength and rigidity makes this box ideal for storing precious materials and documents.

One piece construction, where the cover folds back and the box opens flat. These boxes ship flat and are easily assembled without requiring tape or adhesive. This allows bulk ordering without space limitations and reduces freight and damage in transit.

Dimensions above are inside dimensions, and are 1/2" larger in both dimensions.  
For example, a 4"x6" will have a interior size of 4.5"x6.5"
