Teeth Whitening Pen 3 Pack, 35% Carbamide Peroxide, Effective, No Sensitivity, Easy to Use, Beautiful White Smile, Natural Mint Flavor

These do work! I have seen results; I leave mine on for 5 min without shutting my mouth instead of the 30 sec it recommends. I follow the instructions, no beverages or food for 30 min. I think I go an hour. The application is very easy, swist the bottom till you see a small amount on the brush. A small amount goes a long way, you don't need to squeeze more out for every tooth, I get away with using it on 3 or so. The nice thing it is a small applicator therefore, I can get to my back teeth, yeah! No burning, you will see it bubble up at the bottom of the tooth which is good you know you got it on.

I liked the ease of applying the gel. The plastic pen was a great design. The product was affordable. I was disappointed in the results. The product didn’t whiten my teeth as much as I had hoped it would.

Works ok very expensive for the amount you get. Plus you will twist the product for many many many many twist and no product comes out. RIP off for product beening mostly empty. I thought it was just the 1st batch but its every batch.

I drink coffee every day. After using this a couple of times, my teeth have already become whiter. I love this pen. I recommend it to my friends who drink coffee. There were a few stains I can't find anymore because it got rid of them. It doesn't taste bad either. Don't swallow the flavoring! Hurt my stomach after eating some, but it tastes good. Cheap but effective teeth whitener.

I bought this hoping it would work because I hate using those strips and trays. The instructions say to dry your teeth, put a thin layer on your teeth, and the keep your teeth exposed to air for 30 seconds so it will dry, don't eat or drink for 30 minutes. I did all that...here's the problem, IT DOESN'T DRY. So when you close your mouth, it all comes off right away. Total waste. However I am keeping it to put in trays I have because it was so cheap. I think the ingredients are fine, it just that it can't stay on your teeth long enough to make a difference.

It is simple and easy to use without the mess of a tray or time sitting with a tray in your mouth. It doesn't leave a bad taste either. Definitely makes a difference in whitening.

It’s okay results don’t last ling I’ll stick back to my other kit from ebay

I didn't intend to buy this at first, I was just browsing. But i got it because it didn't cost too much and I'm glad I did. I drink a lot of coffee so my teeth have some stains, but I have already noticed the difference after a couple weeks. The instructions on how to use it are clear and there is no bad taste in my mouth.
