There are some limitations to this trick regardless of whether you get it from Tenyo or Jon
Armstrong. You will need a surface that the plunger does not stick to like a close up mat, table
with a cloth on it, or drink coaster.
The gimmick is easy to use and always ready to go.
It should last a life time. If it does not then it would not be hard to create a new one from an old
deck of cards.
The plunger is well made. You can do the entire Tiny Plunger routine with
some very basic card handling.
