또또혀니
저도 치실 다 떨어져서 사야하는데 이걸로 사볼까해요
In the past, brushing alone was enough to remove plaque without flossing, but at some point, I started feeling uneasy and like I hadn't brushed enough without it. So now, I make sure to floss at least once a day.
First of all, it's uncomfortable to use if the floss is too thick or too thin, but this one is a normal thickness and really convenient.
The length is also longer than I expected, so I can use it for a long time.
