Back in stock! Popular item purchased in December. Colgate Optic White 02, 85g, set of 2, in the latest packaging. We will ship it in an eco-friendly [no box] package. Purchased December 2025 Expiration date: October 2027 Recommended for Optic White fans, and I use it myself. The conventional version claims to show results after one week of use, but this latest Colgate uses a new whitening formula containing millions of active oxygen bubbles, claiming to whiten teeth in 3 days. This active oxygen bubble reaction generates O2 active oxygen (a type of whitening enzyme), releasing a large amount of ultra-fine bubbles to gently whiten teeth from the inside out! The toothpaste warms up as the ingredients react. I also love using it because you can feel your teeth whitening at this time. It feels refreshing to use and foams well with a small amount. The design has been updated with a clear cap, making it stylish. We plan to ship in simple packaging. Please understand that the box may be dented during shipping before purchasing. We do not offer discounts. Thank you. Latest version: Colgate Optic White 02, 85g, set of 2
