At first sight, I had doubts about the glass bottle lasting in my household of young kids.
However, a few drops into the sink and onto the floor tiles, it hasn’t shattered as yet (fingers crossed)! The feel of the floss is thicker than mainstream floss and actually feels like fine string.
I found that I had to change the way I flossed my teeth, it is a plant based material thus prone to breakage. Therefore you can’t floss your teeth in the same place on the floss string, or it will break. You’ll need to use approximately double the length you would compared to mainstream floss.
After the first few attempts, I now have graduated to guilt-free flossing!
