Very nice quality and gets the job done
Color: Silver
This has been the best derma plane razor that I’ve bought so far. I love that it has all of the refills and I ended up buying one for my daughter as well.

High quality dermaplaner
Color: Silver
Great quality metal and the handle has a nice heaviness to it, making it easy to hold and use. the replacements are easy to replace and the feel of my skin when I'm done feels like a baby's bottom

Works well
Color: Silver
Very sharp and efficient. The top was stuck when I first opened it and I got cut but it’s ok. They work well.
