Since the original Bowler's Tape was invented by Chris Keller, many companies have tried to duplicate the original product, but have failed over and over again.

As WE ALL know this is not the case in any of the products made available to us today. We have searched worldwide to find the raw material and the craftsmanship to supply a product as good, or even better. Introducing Bowler's Tape. Inventors Reserve.
