One reason is that I almost didn't buy these because of a review on here that said they didn't come individually wrapped. My family uses it every time they pick their teeth after dinner. After eating food is left behind in the teeth, brushing time cleaning can not be used to help itI really love using these. And what a great bargain! Do you want clean and healthy teeth? Then, you have to floss every day after meals. which will clean up the food left in the middle of the teeth, not become inflamed, and protect your gums. It's also easy to use, allowing children to develop their own habit of keeping teeth clean.
