(Purchased with my own money) Atomy interdental brush

This is the Atomy interdental brush I use.

There are two types: white and blue.

The difference is that the white one has a thick brush, and the blue one has a thin brush.

It is recommended to choose and use it according to the condition of the spaces between your teeth.

If you bend it from a straight position, it stays in that state, so it is comfortable to use in that bent state.
