I recommend Jeniton's waxed dental floss!

This is dental floss made with a soft texture.
There is also a style of dental floss that is a bit firm and irritates the gums when it touches them.
This is on the softer side, so after trying it out, it's an item I've been buying with my own money ever since.
The container is colored but transparent, so it is good because you can roughly tell how much is left without opening it.
It's small, so it's convenient to carry around.
I keep one at the office and one at home, and I use them all the time haha.
If you are looking for soft dental floss, I would like to recommend this! It's also quite affordable at around 3,500 won.
It isn't a big burden.
