It's a cartridge, it's okay. A little tricky to figure out at first how to change it. Also, it doesn't give a good finish or Smooth finish, if you are a woman willing to use this, it's not that good.
My dad uses this.. the blade is good...gives clean save.
Don't know what kind of review you're looking for in a razor blade but it works fine. And remember to discard it after two uses. ❤
Normal razor blades but expensive.
