??Nozzle Material: High Quality Hardened Steel, Ensure The Best Quality!
??The Nozzle is High Hardness -- Overall hardness: 50, Surface hardness: 55-60. More wear-resistant and has longer life.
??Because the nozzle is hardened, So it looks black, The coloration variance is normal and doesn’t affect function
??For 1.75mm Carbon fibre, Filled PLA, Glow-in-the-dark Filament
??About 0.4mm nozzle and needle can not pass, we hope everyone can understand. Because if the nozzle and needle are both accurate 0.4mm. They are impossible to pass. If the nozzle is accurate to 0.4mm, the needle must be smaller than 0.4mm. If the needle is accurate 0.4mm, the nozzle must be bigger 0.4mm.
