Works just as well as the OG, but for much less
This is a perfect and less costly way to get microneedling cartridges for my Dr. Pen M8. They fit perfectly and work just as well. They come with all kinds of precautions taken to keep them sterile, which is very important with something meant to reach down into your skin. The pins are just like the originals and honestly I can't feel any difference when using it. There's no need to pay more for name brand when these work just as well. I'm always a bit cautious because so many off brands aren't just cheap in price, but in quality. Not these, they're the real deal. You can save money and get replacement cartridges that will do a great job.
