Premium Pearl Whitening Gel Pen – 4mL

The brush tip makes it so easy to swipe the gel right along my gumline without making a mess, even in the car. I've been using it after coffee at work for a week and it's already become part of my daily routine.

The 4mL tube is tiny enough to slip into my jeans pocket, so I've been using it right after lunch at my desk without anyone noticing. The gel goes on clear and doesn't taste bad, and my teeth feel noticeably smoother by the end of the week.
