I have handled 95% of the items that Tricks Co. in Japan had in their catalogues but this is the first time I have ever seen this one outside of the catalogue.
The magician introduces a clear cube and thru openings in the side two silks can be shown. A glass is placed on top of the cube and it has a silk in a different color inside. The glass is covered with a tube. Suddenly a silk appears knotted between the two silks in the cube. The tube is lifted from the glass and it is shown that the silk that was previously inside the glass has disappeared!
Very easy to do. Incudes all that is needed in good condition. Instructions are in Japanese but I will provide the buyer with a short English write up.
If you collect Tricks Co. items than this is one that misses in most collections.
