It is an interdental brush from Yuhan.

Each interdental brush has a cap on it, so it is hygienic.

You can easily carry it around.

It is made of soft rubber material, so it is not slippery even when wet.

You can trust it because it uses special medical-grade coated wire.

The quantity is a bit small compared to the price, though.

The handle is comfortable, and I am satisfied because it is a product made by a trustworthy company.
