I found this on the market at a stand where they sold household and technical stuff. The lady selling it told me if it doesn't work she can exchange it. Hm. I had no idea what it is supposed to be used for neither what I'd use it for so I just said yes and thankyou. It's cool because it can move like a fish and you can stretch it out or push it together into a little packet. I was considering to make it into a necklace, my friend said it could be a cigarette holder... now its a ring!!!!
