So back when I got the Raven, I had the tendency to try the gimmick without reading the instructions. I recently found out there should be a catch for it which I remember being in the box but have since lost. Can someone send me a picture of what it looks like so I can make another one. And from what I remember, the ring of the catch is some sort of flexible band. Where can I get one? Can I just get a replacement from somewhere? Thank you!
