I ordered these tips a few months ago because I wanted to try different tip sizes for better speed or quality depending on the situation. Sometimes I use glow in the dark, wood and some other fibrous materials. The (real) .4 hardened steel bits I've used have been excellent, but I haven't been able to find many h/s options in other sizes. I've just started using them as I've also ordered some regular brass nzls and am trying to only use them on threads that need them. The 2 I tried clogged constantly and when trying to clean them I used side cutters to easily clean the hot nozzles (which I often did with my h/s .4s). The results of this action are shown in the attached images. On the nozzle on the left in the pics you can clearly see that they are actually just brass (or maybe copper) with a *very* light coating to make them look like h/s and very soft. I highly recommend looking elsewhere and 100% believe the seller should change or remove the listing and it is highly unethical not to do so. Buyer beware
