I use this mouthwash and it's good.

This is mouthwash. Many companies produce mouthwash, and I think I've tried almost every brand out there. Among them, I'm posting about Yuhan Corporation's Medi-Gargle, which I recently purchased. It is slightly cheaper than other brands, but the sensation is similar. It is almost transparent and has a moderately refreshing, cooling sensation. It is neither too spicy nor too bland, so it is easy to use. I buy it in a large size, and the value for money is quite good.
