Is this item still available? I have seen videos where this illusion is performed with different cloth. One is with a circular/square frame and the other is just a straight rod. Does this trick comes with the box, the gimmick or just an instruction guide?

Until his Death it was available through Pauls website, but since he passed away I have not seen it for sale except at a local 2nd hand market for magic supplies.

The effect was based on Nick Einhorns original In-Flight. On Nicks website you can find his current version which is called In-Flight 3.0 and the presentation looks the same as Paul Daniels's.
