(Purchased with my own money) Perio White Now

I bought it at Olive Young.

It tastes a lot like toothpaste, so it’s fine.

I didn't like it because the user experience was hit or miss due to the saliva in my mouth.

It sticks well on some days, but the adhesive is too weak on others.

Depending on how you use it, it is also a bit difficult to avoid contact with the gums.

I think it would be good for people with large teeth to use.

And there is a color chart, so it is good for checking teeth.
