Systema dental floss

Brushing alone often isn't enough to leave a fresh feeling, so I always use this.

It is dental floss.

It swells gently when touched by saliva, and is small between the teeth.

It removed foreign substances.

Also, because the used thread part swells up quickly

It is easy to check the usage area, allowing for more hygienic use.

It has a groove, so it is very easy to use even when opening and closing.
