Interdental floss for oral care

These are interdental brushes I bought several of in Japan. Of course, I use domestic ones just fine, but since I use these frequently, I tend to stick with them all the time haha. It seems like flossing after meals is a must. The floss is definitely thick, so the durability seems pretty good. I realized I can't go without flossing anymore. My teeth are all over the place, so I have a lot of problems... lol
