I recommend Systema sponge dental floss.

I recommend Systema sponge dental floss!

It is dental floss that swells up when it comes into contact with saliva.

I am on my third pack because it is less irritating than regular dental floss.

Even if it isn't Systema floss, sponge floss is available from various brands.

If you are looking for soft dental floss like me, try using sponge floss!

The price varies depending on the seller, but I bought it for between 2,500 and 3,000 won.
