I 've always thought it's easy to underestimate Tenyo - with the plastic nature of the props and the price, you could easily be forgiven for thinking their products are probably more like 'toys' than hard-hitting magic. I thought I had a pretty good idea of how this would work, but I was wrong. It is very clever, it is easy to do, and it has baffled the small number of people I've performed it to so far. An excellent effect and, at this price, the other 'miracle' is how Tenyo make any money! It really really should not be underestimated.
