GC Ruscello B-20 Picella 牙刷 5入組

The 4-row flocking really gets into the gaps between my teeth, and the handle is slim enough for my smaller hand. I've been using this for two weeks and my mouth feels noticeably cleaner in the morning.

I wasn't sure about the compact head at first, but it reaches my back molars much easier than my old brush. The handle is slim enough to grip comfortably, even with wet hands.

The 4-row flocking gets into those hard-to-reach molars without any fuss, and the handle's grip feels secure even when my hands are wet. I've already ordered a second set for travel—these are my new go-to.
