What a great idea! I loved this product, as I could use it on the smaller children, and not have to worry about sprays or thick rubs you need to apply to their nose to keep them from catching germs. Or the thick chewable tablets that taste awful for adults, and we are expected to get the kids to chew and then swallow this stuff! Well, this item was so unique, as you just take a cotton swab(a pack of twenty are included) and put a few drops of the solution onto the end of the cotton swab, and then in a circular motion run the swab just inside the nostril about 3 times and that it! It smells citrusy like oranges, so the kids were not fighting me to pull away and crying that it hurts!!! It smells really really good, and then the scent goes away and you never even know you have it on! If this is as easy as it gets, I can do this, and make it part of our daily routine, if it helps us to keep germs at bay, and stops the colds and flu I will be keeping this on hand! Give it a try, you will be amazed!!! You can see it for yourself at: www.nozin.com.
