Floorfloss Used about 2-3 times. (Please check the remaining amount in the photos) I cut off and use it each time, so I think hygiene is not a problem. I'm selling it at a low price. I think the regular price was about 3,000 yen. Please refrain from purchasing if you are nervous about used items stored at home. -- 250m of Italian-made fluoridated dental floss, perfect for oral care. - Product name: fluorfloss - Country of manufacture: Italy - Contents: 250m Dental floss made for periodontal disease prevention, gentle on the gums.
