|Puzzle Master's Mirror Image|
This puzzle is one of Puzzle Master's own brand and comes in their standard clamshell package with the insert explaining that the aim is to remove the shuttle (they call it the handle). When solved, the string remains wound onto the large interconnecting ring. It consists of 2 "mirror images" with a string attached and the shuttle entwined through a ring and around the string. The shuttle cannot just slide off due to the presence of a ball which will not pass through. It has been rated as a level 9 (Gruelling) out of 10 - I don't actually think it is quite that tough, more of an 8. When unfolded, it is 15.2 x 7.5cm and yes, it jingles!!!
No solution is provided (and the more experienced of you shouldn't need one) but if you find that it is required (hopefully only after several hours of trying!) then you can download one from here.
