Handcrafted by artisans right here in the USA. Recesses in the wall between studs. Easy installation. Simply put construction adhesive (not included) on the back side of the frame and push it into the opening in your drywall. It will glue to the outside surface of your drywall. Or you can screw it to the studs on each side. Seven fully adjustable glass shelves use our own patented shelf supports. The shelves slide in, then install the included shelf retainers, and the shelves cannot fall off or come out unless you want to move them! Perfect in an earthquake zone.
