The safest dental floss

To be honest, I wasn't used to using dental floss, so I was relying solely on toothpicks and brushing like an old-fashioned person. But one day, brushing wasn't working either, so I bought this product on my sister's recommendation. I purchased it at a great price because it was on sale at Olive Young. It's designed to be really easy to cut, and I love that it's only in the 3,000 won range. I heard they have buy-one-get-one-free deals sometimes, so I'll have to keep an eye out for that too.
