Works as expected.
Size: 2 Pack Pocket Size
Does what it should. Doesn't last as long as I had hoped, though.At least it doesn't taste bad.

Very handy and does the trick
Size: 2 Pack Pocket Size
These are pocket size and just a few squirts and your mouth is moist and refreshed. Not too heavy on the mint flavoring which is a good thing
