32PCS Mk8 Nozzles 3D Printer Extruder Nozzles Hardened Steel, Stainless Steel, Brass High Temperature Pointed Wear Resistant Nozzle 0.4mm,Compatible with CR-10, Ender 3/ V2 Ender3 pro,Prusa i3

Really on use the brass ones. Plenty of .4 in this package. SO far so good. Extremely happy and pleased with customer service.

This was a really nice kit of assorted nozzles. I thought it was an assortment of brass and steel but it was various sizes as well which allowed me to discover a whole new world of printing. I love a .6 nozzle and would have never have intentionally tried/ordered a .6 nozzle. Not sure what other products this seller has to offer but I am very satisfied with this purchase. Happy Printing.

Great Kit! I am not the greatest with knowing information with 3D printers but mine was clogging at first and now it works great. And I also thing I got some extras.

Nice kit that includes hardened nozzles for more abrasive filaments. I run wood infused PLA though them with no issues. Good price too!

Had a bad blockage and bought this kit. Fits with no issue and has good print characteristics.

Great value

Was having extrusion problems after I put these on and noticed that the hole size in nozzles that are marked identical sizes vary which suggests poor tooling. Swapped them out and extrusion improved drastically. I was having the same problem across multiple nozzles from this pack.

The nozzles seem to be as advertised. The steel ones stick hard to a magnet, so theyre the real deal. The stainless dont stick at all, but that doesnt really mean anything. The one truly phony thing is the needles. They are all the same size and they measure exactly 0.34mm-they are neither 0.4 nor 0.5 as advertised. I have purchased other needles for sizing, and they are that same 0.34mm size, so all I can say is that each nozzle here allowed the needle to drop through easily, so none of them are undersized. A good set that covers many filament scenarios. As advertised except for the needle nonsense.

I have had to use 4 nozzles for 2 prints. Basic filament, nothing snazzy. These nozzles clog the second filament enters them. Both materials, brass and steel. Fortunately they affordable enough Ill just have to keep swapping nozzles.....total pain.....and get OEM nozzles. Live and learn.

Quality product and Amazon delivery was smooth and quick.
