Here is what the puzzle maker said about this puzzle in the sale listing:

"Reminiscent of Padaung Rings, this nifty little pocket puzzle is a lot of fun to solve. With a level 14.4.2 it's tricky but not impossible ... once you get the correct alignment and piece selection, it flows fairly quickly."
