As usual, it comes in immaculate Hanayama packaging with the unsolved puzzle tied to a board and a leather thong (No you idiot! Not the underwear!!!) attached to it. I presume that you are intended to wear it as a pendant on the thong once you have solved it - I think I will pass on that - they are attractive things but not that attractive! It is rated as 1 (out of 6) by Hanayama and 5 out of 10 by Puzzle Master. Believe me, you will not need a solution file but if you want one for your collection then you can get it here.
It consists of 2 chromed pieces of metal which are wound together via a corkscrew cut out on the shafts and there are magnets in the free ends to hold it together when solved. When it arrives it is obviously unsolved and so doesn't form a complete ring. A quick fiddle unwinds it (rather satisfyingly) into it's 2 components and then you need to work out how to wind it back together but this time forming the complete ring.

Whilst being very easy, it is quite satisfying to play with repeatedly - it makes a great worry bead (I love fiddling whilst watching TV, it makes a very satisfying clink as the magnets pull together!
