Dental floss beginner's item

I've never used dental floss before, but I bought this to start using it diligently this year. A friend told me it's like a basic essential, so I chose this one. I haven't tried other floss brands, so I can't compare them yet, but it seems pretty good. If you don't use it every day, it lasts for several months. The capacity is 50m, and even after using it for over three months, there is still some left. It's lightweight and seems to be on the smaller side, so it's easy to carry around. I bought it at Olive Young.
