상큼이로다
다이소에도 치실이 나오는군요
I recommend Daiso Double Line dental floss for oral care.
At 3,000 won, it is on the expensive side for a Daiso product, but since there are so many floss pieces, it is a good value for the money.
It effectively removes food particles stuck between your teeth and is hygienic, so you will be able to use it comfortably.
