Keyword: Oral tongue cleaner

It's a Daiso tongue cleaner.

It's 1,000 won each. As you'll see if you go to Daiso, there are packs of a few for 1,000 won, but I chose this one.

I didn't originally use a tongue cleaner.

I bought it, and wow, it's so refreshing!

It's worlds apart from brushing with a toothbrush.

I liked this one even more because it's made of hard silicone.

I recommend it.
