Cost-effective dental floss

I stock up on this Daiso dental floss and use it.

After using Oral-B, I do it thoroughly once more with a thin dental floss product from Daiso.

It's affordable, lasts a long time, and is a total god-tier value item.

I underestimated it because it's Daiso, but it's really good for rough use!!

For beginners, don't use expensive stuff; try practicing and using this instead.
