I bought this for use with the "Perfect Bill Tube" and I am glad I did. The tube did come with a bill vanishing silk but it was cheaply made. This Vanishing Handkerchief is much nicer, the silk is thick and and smooth, which helps the gimmick work properly. I got the red version of this and it is very attractive. The only problem with this handkerchief is the way the gimmick is folded. It was a simple matter to remove that and replace it with one that was consistent with the bill tube trick.
