Daiso interdental brushes are good.

I’ve been using the Daiso interdental brush because it’s affordable and offers great value for money. My dentist recommended using interdental brushes. I started using one after the recommendation, and I found it effective. If I don't use one and just brush my teeth, it feels like I haven't really brushed at all.

I think it's good that Daiso interdental brushes come in various sizes.
