the razor blade market is really a world of Ugly The shops (even told the sell discount hyper expensive), I do not know that between the manufacturer and the seller margin "to death" but it is obvious that some line their pockets on our backs (well on our hair), c It is shameful. I'm looking for even cheaper, each blade must cost less than one euro to manufacture (even if that ca not be trademarks of blades but compatible blades)
