Pseudo Secret Ring Box is a decorative (well, the best I could) "secret" ring box with a twist (sorry...). Grasp the top, twist the bottom 180 degrees, and the ring box opens. Keep twisting another 180 degrees, and the ring box closes. Small neodymium magnets in the shell halves assist in aligning and securing the shell halves.
As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make mistakes in plenty.
