Magic Tricks

Well, considering that I advise against it as an opener, that would be a fair conclusion ;-)
I have used it as a last trick closer for a 'set', whether in a formal setting or impromptu. Opening the 'door' for a peek at the card is strong...erasing the door at the close of the trick is powerful. When coupled with the fact that the card box is examinable...well...*POOF*...minds are blown!
Obviously, its too small for a stage performance, but for those smaller, more intimate audiences, this would be a great closer.
Have you placed your order yet???

You could!
In fact, the deck is your normal everyday Bicycle deck. You'd have to 'ditch' one gimmick which would be very easy to do, especially since everyone is checking out the box at the end of your performance.
One thing to consider, I personally wouldn't lead into a routine with this trick because it plays HUGE. Anything w/cards after this, in my opinion, would be a potential letdown.
Nonetheless, Little Door is outstanding.
You'll have to pre order this to get into the cue and estimated delivery dates have slipped 3 times already (June 10th to the 17th, now the 24th). It's not unlikely that it will slip again. The gimmick(s) must be hand made. Don't worry...they are of great quality.
Plus, plenty of orders in front of you.
However, if you can handle the anxiety of a long wait, this is absolutely the trick to wait for!
No, I don't work for PM, nor do I get any consideration for my 'kudos and props' for the "Little Door" trick.
Best wishes...

Could you/ would you use it as a closer to a card trick routine?
