I had this puzzle given me some 8 or so years ago, I presume it is a PEN BOX Puzzle and I am hoping for help to open the box. I know it initially needs a magnet and have successfully moved one end panel just a little, but then I get stuck. If you have seen this puzzle and know its name and how to open it, I would appreciate your help. Attached are photos as best as I could get.
