Teeth Whitening Pen (2 pk), 20+ Treatments Each, Instant Teeth Whitening, No Sensitivity, Whiter in 1 Minute, On The Go, Easy Brush On, Best of Teeth Whitening Pens, 35% Carbamide Peroxide

Everyone in our family has custom bleaching trays from our dentist. Except my husband...He has tried the route of dipping a tray in water and letting it mold to your teeth. Didn't like it. This is truly the way to go. It goes on easily, no mess and yes it really does whiten. He loves it when we travel, quick and easy to take along, while we are hauling bleaching try and gel. Before investing in tray, give these teeth whitening pens a try.

Probably not the whitener, but my mouth piece..yuk! Tastes fine but I like the 44% better.

Me parece bien pero no te los blanquea al minuto, espero que con el uso se vea diferencia, pero to pensé que tenía un efecto rápido y no , pero funciona para irnos blamqueando con el tratamiento y su uso

This is hands down the best teeth whitening product I have ever used. I work in the fire service and we don't have the most ideal hours which makes keeping your pearly whites not so white. This product taste great and took years of coffee stains away because you know how much coffee we go through on a 72 hour shift. I highly recommend this to anyone and stop wasting your time with the other products.

Like another reviewer wrote, I couldn't get any product to dispense from either pen. Hundreds of clicks, but no product. Packaged up the pens, and submitted a request for a refund. Prior to sealing the envelope I noted product gel oozing from the pen. Cancelled the return and decided to try and used them, thinking somehow they both suddenly worked. Unfortunately each pen only had enough product to last for 3 days! Sooo disappointed. Clearly defective!

First time using a pen type whitening product. It took a lot of clicks to get the gel going (not different from many of click-pen type products though), but overall I like it! I used it after drinking a cup of black coffee and it’s nice for a touch and go solution! I just keep it in my purse and apply whenever I need to, not too messy at all.

I was incredibly hopeful after reading the reviews, but after using the product for a few weeks, I have not seen any difference in color. My teeth are not sensitive, so that was a plus. The taste was fine and it was super easy to use. If my teeth looked whiter, than this product would have been well worth it.

I have whiter teeth now that I went through the entire pen. I had a mouthguard and laser device, so I was able to speed it up. I know, many of you think it doesn't work, but there are scientific experiments showing the LED activation does indeed make a difference. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4911750/I liked the pen design and brush application.
