Floorfloss I bought this after it was recommended by my dentist, but I've decided to switch to interdental brushes, so I'm selling it. I used the main unit for a while to try it out, so I'm not sure exactly how many meters are left, but it's as shown in the third photo. I think there's still plenty left to use. The refill is new and unopened. - Model name: fluorfloss - Size: 250m - Country of manufacture: Italy - Intended use: Dental floss Thank you for looking.
