The product I am introducing today is the Oral-B Essential Floss.
It is easily accessible as it can be purchased at large supermarkets.
I bought it cheaply at E-Mart during a buy-one-get-one-free promotion.
The dental floss is coated with wax, so you can easily insert it between your teeth.
But after cutting the thread, it often got tangled inside the tube.
So there were times when I had to open the case and take the thread out again.
Nowadays, I pull the string out a bit longer, leaving about 1cm outside the lid when using it.
