🦷 4 ml Professional Teeth Whitening Pen with Ultimate Strength 44%. Compact and Portable with Soft Applicator. No-Leak Cap. Effective and Safe for Sensitive Enamel. Review

I haven't noticed much difference in using this pen compared to some other pens I've tried. My biggest issue is that so much leaked on arrival and continues to seep into the lid.

I really liked the ease of use of the whitening pen and saw results within the first 2-3 days. I'm a big coffee drinker and was glad it helped whiten my teeth a shade or two. Fast and easy!

I love how easy it is to use, especially for someone who travels constantly. Also, after a few whitening strips, my teeth no longer hurt at all.

So very easy to put on, no need to brush out as it will be gone in an hour. Def works, you just have to be consistent with it. Not as good as professional stuff that takes longer, but good for in between.

This product works as advertised. I had no problem applying the product to my lower front teeth which were more stained than my upper teeth. Good work. No sensitivity problems.

Love how easy it is to use, especially for someone who travels constantly. Also, after a few whitening strips, my teeth no longer hurt at all.

Stained teeth from coffee and smoking is not a very pleasant sight and I wanted to brighten my smile. I decided to try the teeth whitening pen and am glad my teeth are getting whiter. The handle is easy to use.

So it's very easy to build a relationship, you really don't have to dismiss it because in an hour it's all gone. Def works, you just have to be consistent with it. Not as good as professional stuff that takes longer, but good for in between.
