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.

When used daily, it is easy to so the effects. It's easy to use, just twist (crank) until you see the gel and brush on. Be sure to follow the instructions.

I tossed all three in the trash because that’s what they were. The mechanism didn’t work, yet they leaked all over my hands. They tasted like vinegar and left a dry feelOn my lips and mouth—yuk!!!

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.

Garbage all pens broken and leaking. Tried to get some out anyway and they don’t even work these are the twist type syringes and defective. Garbage don’t waste you money or time.

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 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.
