Crest3D White Glamorous White Whitestrips - 28 strips (Pack of 2) - Packaging may vary

After a few uses...noticeably a few shades whiter more then expected w/out the hassle of trays and solution that I went through with my dentist years ago. May not need to go through the full 2 pack as I'm not looking for the shine in the dark teeth. The lower strip is small as others have commented but my lower jaw is small so for me it fits perfectly.

These strips are thinner and I read that's because of the hydrogen peroxide content, but they do not stay in place and after a few minutes are falling off so results are poor. Other white strips are thicker and stay in place so you get the full results of the strips. I really regret purchasing this item and will not order these next time.
