Review on 🦷 Cali White Teeth Whitening Pen - 35% Carbamide Peroxide Gel, Made in USA, Instant Natural Whitener, Easy-to-Use Brush for On-The-Go, Professional Results, Sensitive Smile Safe, Organic Mint - Vegan & Organic by Tony Bennett

The only good thing about this whitening pen is that it's vegan, not tested on animals and doesn't contain any animal products. I've read reviews of other products that didn't mention animal testing, which is important to me, so I decided to give this product a try. First, there is no instruction to turn the bottom of the handle to get the liquid flowing. Understood, but even just an arrow pointing around would be nice. Second negative, not much lightening, maybe I saw a little but not enough to say wow! Third, the amount of gel released is either almost non-existent or too much. The fourth scam, can't tell how much is left. After a week I think it might fail but I can't say for sure or the rotating mechanism just stopped working. You can see some gel at the top, but is that all that's left? I will not buy this again and I will buy a "bite" product that has a glass bottle so you can really see what's inside and have a lot more control over how you apply the gel.
