사용한 부분이 부풀어 오른 다니 신기하네요
This is the dental floss I always use before brushing my teeth.
I've tried various types, but the Systema sponge floss I'm using these days is good, so I recommend it.
The floss swells up when exposed to heat, so even though it is sponge floss, it seems more hygienic because you can see the used parts.
I am also using interdental brushes, but it seems like dental floss removes debris more precisely.
It’s a bit of a hassle to use every time before brushing, but I think it’s really good to use for dental health.
I recommend Systema sponge dental floss.
It's also great as a value-for-money item.
