Crest Plus Scope ยาสีฟันไวท์เทนนิ่ง - 0.85 ออนซ์

The full-size tube is great, but this tiny 0.85 oz. travel version is perfect for my gym bag, and I love that it fights tartar and whitens at the same time. The minty flavor lingers for a good while, and my teeth feel noticeably cleaner after each brush.

The whitening effect is pretty subtle after a few weeks, which is fine since I mainly bought it for the fresh taste. It does kill bad breath germs and fights cavities like it says, but the 0.85 oz. tube is way too small for the price.
