I recommend oral care products.

This is dental floss sold at Daiso! The floss size is 840D, which is a good size for general use! You can purchase it for a very affordable price of 1,000 won! Although it is labeled as mint-scented, the scent isn't strong, so it was pleasant to use without any issues. I use it to thoroughly clean between my teeth, and dental floss is an absolute must for anyone looking to take care of their oral health!! It is easy to buy anywhere and affordable, so please give it a try~
