손잡이가 있어서 사용하기 편하겠어용
It's not Oral-B.
It is dental floss made by Oral Finish.
The floss part is comfortable and good, just like regular disposable floss.
But maybe because it's adult dental floss, the other end is super sharp.
I think this is both an advantage and a disadvantage.
It's the best for removing things stuck between your teeth.
If you grab it wrong, it stings so much you'll be surprised haha
Still, it's comfortable, so I'm using it well.
