I like using a tongue cleaner.

Hi, this is the tongue cleaner I use~^^ I bought it at Daiso, and it's great value for the money. It's the type that tapers slightly from top to bottom, and I like it because it cleans really comfortably! I love how refreshing it feels to finish brushing my teeth with a tongue cleaner. It feels quite soft when cleaning, so it's good for beginners to use too. I recommend this tongue cleaner.
