! Centimeter is the mark of 2 sides, 1 with the mm which is convenient to be précis.que else to say: it will up to 3 meters !! very practical set apart the system jumps when I wound it one because I am not fully satisfied with the seller, I have received my purchase open with the system deteriorated reel every time I have to put it back in its box that serves as the button has wrapped, by cons when it replaced so perfectly wraps I keep anyway despite ..ne gene not seeking to make transaction with a seller if somewhat responsible
