A collection of Cast Puzzles. These are the so-called "wisdom rings," but brute force won't solve them. Each has a name, and how to take them apart and put them back together can easily be found with a web search, but please make that your last resort. No matter how difficult they are, you'll probably be able to solve them within an hour. It's exhilarating. ● Shark, Seabream, Cricket, Crow, Starfish ● Condition: Each has been used for only a few hours by my family. ● Accessories: None ● Other Notes: Please consider this a used item.
