Thank you for viewing. This is a ReFa Crystal Carat Face Roller, which uses diamond-cut balls. Brand: ReFa Model Name: Crystal Carat Face Model Number: RF-CC2007B Included items: Box, instruction manual, pouch, cleaning cloth I used it a few times when I bought it, and then I put it away. There are no noticeable scratches, and I think it's generally clean, but please refrain from purchasing if you are sensitive to used items.
