Interdental brush I bought with my own money

This is a soft interdental brush from Daiso that I bought with my own money for oral care.

It is a Daiso product that is reasonably priced and good for general use.

It has the advantage of being adjustable with three size divisions, so it is very convenient to use in various personalized forms.

It also comes with a portable case, making it convenient to carry around and take out to use when needed.
