FUJI NXT I H08/H12 5.0 Nozzle AA741

General method of determining original NXT nozzles and imitation nozzles:

Look at the QR code. The original nozzle's QR code is very thin, pasted on, the material is aluminum foil, every white dot of the QR code, occupiesevery corner of the quadrangle (four corners); imitation nozzles, because of the cheap cost, use a QR code aluminum foil is very thick, andthe white dotson the QR code, are not even, notfull. (This is obvious from a microscope or magnifying glass.)
