At least they are sterile
These are funny being advertised as dermaplane because they are packaged as scalpels. The 5 scalpels are individually wrapped, and labeled sterile. As the price indicates, they are on the cheap side. Which is fine, they work, but they aren’t terribly sharp so you have to scrape a bit harder than preferred. For dermaplaning I prefer the schick ones as they have tiny serrations which cut the hair better than anything else I have found so far.

Blades are not sharp and will not remove peach fuzz, even after two swipes
Color: #10 - Pack of 21 (20 Blades + 1 Handle)
I was really disappointed in this. It did not remove all of the peach fuzz completely and I dermaplaned twice back to back. Which tells me the blades aren’t as sharp as they’re made out to be. The blade handle was sturdy and seemed to be made of good quality. But the blades themselves are horrible at cutting and aren’t razor sharp. I personally wouldn’t purchase this if I were you. I’ll keep the blade handle, but I will definitely be purchasing different blades.

Good quality!
Color: #14R - Pack of 21 (20 Blades + 1 Handle)
If you are looking to dermaplane at home obviously be careful but if you are looking into getting scalpels, these are good quality and come in a big pack where it will last you a while! Remember dermaplaning is once every four weeks and make sure you have no active breakouts!
