I dont know if Tenyo ever gets a mention but up front I love the brand..there are so many collecters out there its time we came out of the wood work. Tenyo does sometimes make a bad product but in general they are ingenious and self working. Many magicians I have spoken to say that Tenyo is no good because they are made from plastic etc...but in the same breath admit if they were a little upmarket and made from wood say ...use them in their acts.
This one is simple yet effective and just because they are a packet item does not distract from their impact on an audience. I believe I have seen somewhere a magician use only Tenyo items in his acts and he is doing OK..So dont dismiss Tenyo anyone until you have seem the strength of the illusion.
