치실은 굵기가 중요한듯해여
The thickness is important when using dental floss, and I like it because it is just right and not uncomfortable.
You can properly maintain it when you want to clean every nook and cranny inside that cannot be cleaned thoroughly with a toothbrush alone.
I like that I can see inside so I can check how much floss is left. A toothbrush alone isn't enough for oral care, but using floss makes me feel more at ease and helps keep my mouth clean.
