(Purchased with my own money) Plackers Twin Line 300-Pack Dental Floss

I recommend the Plackers Twin Line 300-pack dental floss.

Two-strand dental floss removes food particles between teeth more effectively. It is a Y-shaped floss that is easy to use and hygienic.

To use, gently slide the dental floss between your teeth and use it carefully to avoid injuring your gums.

It's good because they sell it on Coupang and the price is cheap.

It is stronger than other dental floss, and it feels refreshing after use.
