Tenyo is the best. I have tried other cheaper models but the spots fall off etc. They are about $28.00 right now IF you can find one. They will be re-releasing tricks soon with Japanese packaging and English directions. Thing is I am afraid they might be jobbing them off to a Chinese company that counterfeited a lot of their product. If this is the case the product will not be what it used to be. Just wait and see.
If you get an English package you'll know it's an old one.
