Hello TM peeps, wondering if you can help........

So was digging deep into the magic box the other day and i came across this ring........

Its goldy silvery in color and its in a twisted almost "hair style" plated twists....
I recall a trick with it where you twist it one way and it seems to get tighter on your finger and you turn it the other way and it gets looser

I cant for the life of me remeber wer I got it or what its called, does anyone know what it might be ? so i can find more effects to do with it?

thankyou, any pushes in the right direction wud be good thanks xxxxxxxxxxx
