This album-style box was designed for a customer who needed the convenience of our hand-made cloth-covered ring binder coupled with the economy offered by production fabrication. Because it closes like a box, contents are kept completely safe in an entirely enclosed environment. All of our boxes are readily available in your choice of .060 acid- free grey/ white board, our acid-, lignin-, and sulfur- free .060 Lig-Free Type I board, and our patented .065 MicroChamber board, which affords all of the benefits of our Lig-Free Type I board while actively contributing to the preservation of the material it holds. Complete specifications on all of our papers and boards are available here Technical Info. Pages made from archival polyester are available to fit in the boxes and are open on one long side. This long open side also has holes punched to allow insertion into the binder rings inside the box. Search MY-RBB12112, MY-RB15112, or Ring Binder Pages for the pages.
