Extra-fine I-shaped interdental brushes with a soft tip, designed to enter between teeth and clean away debris. The SS size is 0.8 mm. A storage cap can be attached to extend the handle.
Gently move the brush horizontally back and forth between teeth several times. Do not force it into a tight space. If bending the brush, bend it slowly; bending the wire may cause it to break. To extend the handle with the cap, insert it all the way.
