PRGR Ct-440 Iron Set 3-SW 9 Clubs M-43/96 MPH Shafts. I am not very familiar with this set. The come from Japan. I saw another post that the shafts are a carbon base? They look like graphite? They only writing on the shaft is “ made in Japan “ and “M-43/96 mph” I am assuming that means a regular stiffness? There is some lead tape on the back of a few of the clubs. I left it. It is easy to get off if you decide to. The PRGR grips are passable. A few have some peeling at the base but they are not cracking and definitely usable
