We ran across this bookcase with secret storage drawers in the furniture section of Etsy. The bookcase is handmade and is on priced on the higher end, but does include a hidden drawer under each shelf complete with hidden magnetic locks. You can move a magnetic key over specific spots on the exterior to allow access to compartments large enough to store handguns, cash, supplies or other valuables. The entire bookcase is made from red oak, cherry, alder or knotty pine with dovetail joints on every corner.
