The interdental floss I use

I bought both of these products at Olive Young based on a staff recommendation. Back in my twenties, I knew flossing was important, but honestly, I didn't really take care of it because it was a hassle. I thought getting a scaling twice a year and brushing was enough. However, since turning thirty, I’ve realized that as you get older, your teeth are your life, so I’m belatedly putting a lot of effort into flossing. ㅠㅠ It’s still difficult, though...
