Maybe it's magic tape. Not 3M Magic Tape, but tape with some sort of magical properties. Of course, that does assume the "batteries are included" proposition. Or it could be that the dispenser is magic, and imparts its magical properties to ordinary tape.
Of course, again, I am reading more into the product than is in the description simply based on the price. A dangerous assumption indeed.
