Our 11" x 17" aluminum clipboard with storage area from 11x17 is a storage box and clipboard in one. The innovative design includes a rectangular aluminum storage box with a pen/pencil holder. The clipboard is the lid, securing up to 1" of 11" x 17" drawings or documents. The high-capacity clip is centered near the edge of the shorter 11" side.  All edges are rounded on our clipboards with built-in storage compartments.
