Where these two actually differ

  • We flag Fragrance allergens or undisclosed additives and Microbial growth if floss is stored damp on the Floss & Ploss and not on the Listerine.
  • We flag Mint flavoring allergen potential and Gum tissue abrasion from rough edges on the Listerine and not on the Floss & Ploss.
  • The Floss & Ploss is Dental floss (plant-based or silk) and glass case where the Listerine is Nylon monofilament floss, mint flavoring, which is most of the difference in these two grades.
