You unwind some thread from a card, break it into several strands, roll it into a little ball and as if by magic it restores itself into one piece again.
This comes with instructions and is good for Close Up or the largest Stage or Cabaret.
This is the exact thread you need for performing this illusion and easy to break.
If you are doing Close Up consider have more than 1 card set up.
See N001A in Magicians Accessories for Replacements and on this number there are discounts for more than 5.
