First of, this is a fantastic visual opener/closer. The only issue I have with it is it isn't very
small hand friendly. Don't get me wrong, I found a way to make it work for me even with small hands
but it isn't easy. You will have to find a slightly altered handling that works for you if you have
small hands. Aside from this, it is a easy to make gimmick and it is extremely durable. With
practice, the effect is nearly undetectable and highly visual. I've gotten great reactions out of it
so far.
