dental floss bought at Daiso

I urgently needed dental floss, so I bought some at Daiso.

These days, Daiso has such a huge variety of oral care products~ Whether they come in thick or thin thickness, and whether they have a mint scent or not...

What I bought is this!

It swells up when saliva touches it while I'm using it... an expansion thread?

There are many cases where brushing alone doesn't clean everything.

I do it once in a while!!

Let's all keep our mouths clean~^^
