This Dental Floss pick from The Humble Co. is brought to you by dentists who care about your oral health, our environment and children in need of oral care. We recommend you use this interdental product once a day to remove food debris and bacteria from in-between the teeth to prevent bad breath and gum disease. Better for the environment than standard plastic floss picks! Thread made of nylon. Handle made of a mix of 40% corn starch and 60% PLA materials.
