If you want a strong, refreshing feeling, I recommend Listerine Mouthwash.

Product Name: Listerine Cool Mint Mouthwash

I’d like to introduce a must-have item that I always use because it always leaves my mouth feeling fresh.
Listerine is really famous when it comes to mouthwash, isn't it?
I highly recommend this for situations where it is difficult to brush your teeth after a meal or when your mouth feels dry. It leaves your mouth feeling incredibly refreshed.
I've been using it for a long time and have gotten used to the spiciness, but I think it would be best for first-time users to use only a small amount haha.
The size is cute and fits perfectly in one hand.
While larger capacities offer better value for money, I find myself mainly using this product because of its portability, even though it is small and expensive.
