A good mouthwash toothbrush with a wide head

This is a Gargrin fine-bristle toothbrush. I purchased it from the Dong-A Pharmaceutical Mall. I didn't know Gargrin made toothbrushes, so I bought this out of curiosity, and I am satisfied with using it. The design follows the shape of the handle, so the grip is good, and the bristle head is wide, making brushing feel easier and more comfortable.
