puzzle ring

The puzzle ring is a kind of the puzzles.
It is the play that it connects one set of (more than 2) part which it cannot easily take off, and it takes off basically.
But I do not take it off, and there is the thing for the purpose of having parts in specific form.
In addition, I can easily take off most things by a way outside identification, but there is the thing which time hangs over till I take it off even if I take it off because a procedure is complicated and know.

I enjoy the process that makes trial and error to look for a method to exclude.

Metal and a string are used for a part well.
Because the metal cannot change easily, to take it off; obstacle.
On the contrary, because the string is tender; can let pass the small gap.
There are a wooden thing and the paper thing, too.
