I recommend Plackers dental floss.

I have a habit of flossing after brushing my teeth. The one I use is Plackers' kids' floss. To be honest, I used to just brush with a toothbrush and finish with a tongue cleaner, and I was afraid to use floss, but I happened to see a recommendation for kids' floss online and bought it.

It definitely has a handle, so it's easy to use. The thread is also sturdy. I think it can be reused a few times. I think it would be useful for dental floss beginners. It comes in a resealable bag, so it's easy to store, and there are plenty of them. I bought it cheaply from iHerb a while ago.

Anyway, I recommend that beginners use kids' dental floss for oral care.
