If you have ever been on the hunt for replacement Bicycle tuck boxes due to damage or perhaps for making gaffed boxes, you know how troublesome and expensive it could be to find empty boxes. They often sold for more than a box with cards in it.
It looks like the problem has been solved. Surprisingly, they are available in the now "standard" box and the old classic box that magicians favor.
