Not the greatest. Sticks to your lips and doesn't do the job very fiddly not like ones I had before.

Thought I try these out and they work. Like that's there no mess. Try'd 3 strips just on the top to see the difference and there was a much noticeable difference. They are wide enough to cut in half to do top & bottom. Will be ordering more.

Noticeable results in the first few days, definitely gets rid of tea and coffee stains.

Very convenient for on the go. Great visable results.
