Great whitening strips

I buy mine at Costco for around 70 cad. I won’t buy it anywhere else. I use it maybe once every 3 months for however long it says to use. It’s done a great job, you see the difference right after. It lasts as well. The strips for the most part fit well and last on the teeth without falling off for the hour or so you leave it on. It doesn’t leave a gross feeling in your mouth after or a film on your teeth, although you will want to spit out the rest of the product when your done with the strips.
I use sensydine toothpaste right before I apply these just to make sure my teeth don’t get irritated and super sensitive after and it works like a charm. I recommend to anyone.

Can I say Miracle workers!!! All I need is one hour before I go anywhere! Tadah instant white! I love how it works below the surface to get the job done . Love love love it

Using these white strips after years of damaging my own teeth I found they worked effectively and whitened my teeth noticeably,now I can go and smile without trying to hide my mouth

I have been using these strips for a few years and they are great. I have pretty white teeth but about twice a month I use the strips to get an even whiter smile. My husband smokes and he uses the strips and you would never know he is a smoker. It is worth every penny.

I love these! I didn't even realize how white they got my teeth until I saw a picture of myself! My kids used to tell me how yellow my teeth were then one day I showed them and they said, "hey you're teeth are white!" Can't argue with that!
