If you hate overly priced whitening strips these Grinigh Coconut Oil strips are great. With this Kit you get 14 treatments. This whitening treatment lasts 6 months and up. It only takes 1 week until you see a difference. You just need to wear these strips for 60 minutes a day up to 120 minutes if you like. 1 strip a day for 14 days. They are slip free and safe. These Strips are not uncomfortable at all. These strips have coconut oil, menthol, peroxide, and a few other ingredients. You can talk and drink water while your wearing these whitening strips. Don't drink anything but water for the 60-120 minutes that your wearing them. These Strips don't taste bad at all. It only took about 1 week for me to notice a difference. I'm still using them to finish my 14 weeks. These whitening strips use the same enamel safe whitening ingredients that dentists use. These strips go below the enamel to get to the stains. I hate going to the dentist. I'm actually afraid of dentists, that's why I went this route. I got these whitening strips at a discount for my honest review of them. I wanted to give them a try so I got them to tell people how good they were. I'm very happy with my purchase. I recommend these strips. If your not satisfied you will get a full refund. You can't go wrong with this product.
