Dental floss I bought with my own money

This is dental floss I bought with my own money. It is specifically designed for children, but I use it with my child. I have tried regular floss before, but this feels somehow sturdier. My dentist recommended flossing regularly, so I think I’ve been using it for over a year now. I didn't realize it before I started, but once I began, my teeth don't feel fresh even after brushing if I don't floss. I plan to keep using it!
