牙齒美白凝膠＋竹製塗抹器

The 6ml jar really does last ages—I've been using it twice a week for two months and it's barely half empty. My teeth feel less sensitive than with other whitening products I've tried, which is a huge relief.

I love how the bamboo applicator makes applying the gel precise and mess-free. My teeth look noticeably brighter after a month of consistent use, and it hasn't irritated my sensitive gums at all.

After just two weeks using this gel with the bamboo applicator, my teeth are visibly brighter without any sensitivity. The 6ml jar really does last, and the brush makes application quick and mess-free.
