37 5/16 x 4 1/16 x 31" Outer Mirror Boxes

The 37 5/16 x 4 1/16 x 31 inch outer mirror box is the exterior shell of a two-piece telescoping system (inner box INNERMIRROR sold separately), manufactured from ECT-32 kraft corrugated. It pairs with the inner mirror box (sold separately) to create an adjustable set that accommodates varying depths of flat, framed, or panel items without requiring additional packaging materials.

Moving companies, glass distributors, art handlers, furniture retailers, and fulfillment operations shipping large flat items all rely on this format for its combination of structural support and purpose-built labeling. "Fragile Glass" and "Do Not Lay Flat" handling instructions are printed directly on the corrugated surface, eliminating the need for separate warning labels and communicating clearly to warehouse staff and freight handlers throughout the shipping chain.

Each unit weighs approximately 2.102 lbs, keeping manual handling practical even at volume. Boxes are sold in bundles of 10 and ship via parcel carrier.
