This puzzlering is not a very expensive ring but it is by far my favorite ring. I like that it is a ring with a twist, as it can be taken apart without coming completely loose. And with a little luck you can put it together again.

No one knows the exact history of the ring. Some say it was supposed to keep women from cheating while their husband was out of town. Assuming you can't take the ring off without it falling apart.

Others say it stands for a bond between brothers.

I personally think the first one is funny, but has its flaws. The second one seems more logical :)
