The nested box effect is a well-known classic to magicians, but spectators will still be amazed.
This version is a very economical way to perform the effect. The set is large enough to appear
substantial but small enough to travel with. The quality is "enough," meaning it doesn't look bad
but it's clearly not going to win a woodworking award. That's fine, because the more ordinary it
looks the better in terms of avoiding suspicion.
This effect requires no technique at all
to load or present an item in the box. However, you will need to supply your own way of vanishing
whatever you want to put in the box using sleight of hand, a vanish device, or otherwise. You also
need to supply your own lock if you want to use a lock (the useless ones that come on suitcases are
perfect), but the lock isn't really essential if you don't feel like using it.
