I remember trying the Listerine cool mint strips years ago and I was surprised at how strong they were. When you put the strip in your mouth and breath in, a strong cool scent goes through you mouth, throat and nasal passages. It definitely is a lot stronger than other mints or gums out there. I will say that these are a little better tasting than the Listerine mouthwash, but if you don't like the mouthwash you won't like these. The Listerine strips are so handy to have in your purse, car or at home. The container is really small yet it fits a lot of strips in it. In fact it is so small you could fit it in your pocket and barely feel it in there. I like these because I hate having bad breath and these really help with that. Other gums and mints last a very short time, but this one seems to linger in your mouth longer. You can buy these in single packs or in bulk. I just bought some more of these the other day to use. They are strong, but they work.
