상큼이로다
다이소에도 혀 클리너가 파는군요
I don't know how many years I've been using this.
First of all, the price goes without saying; you can easily use it for a year for just 1,000 won.
Brushing doesn't really clean the bottom of the tongue that well, but if you sweep it thoroughly with this tongue cleaner, it gets really clean.
However, if you do it too hard, your tongue will hurt, so if you use it gently, it is truly the best value for money.
