Review on 🌟 Advanced Teeth Whitening Pen - Pack of 4 Pens, Over 40 Applications, Highly Effective, Painless & Sensitivity-Free, Travel-Friendly, User-Friendly, Achieve a Brilliant White Smile, Refreshing Natural Mint Flavor by Chelsea Hunter

I love the ease of use of this product. I use it in the morning or in the evening. But it's so comfortable that it can actually be carried around and used throughout the day. The bleaching liquid is very effective. I have used professional whitening products from the dentist which are too strong and attack the gums. This product is just as effective at whitening but doesn't damage my gums at all. So I can safely apply it directly to the gum line. I highly recommend this whitening pen to anyone who wants a snow white smile ready for photos.
