## Description

Scientifically formulated nasal gel blocks virus-sized particles, providing extra defense against cold and flu. Easy, mess-free application for all-day protection.

Review: The nose feels clear and free from irritation after using this product and going outside. - Outstanding product, really does what it says, the outside debris including pollen and viruses are stopped immediately from entering the nasal passages. I would unequivocally recommend this product, it really is absolutely fantastic. Great value for money, good pocket size, not abrasive but moist and easy to use. 100% perfection.
Review: Top product. Always carry a tube. - Wouldn't be without this product. Just a small amount gives you a lot of protection in crowded places. Every time I use air travel and apply this I don't get a cold. Good value because by using a small amount a tube can last two years and there is no expiry date. No smell. No longer available in shops.

### ⭐⭐⭐⭐ Cold defence
*by Z***I on 23 November 2024*

Amazing product that should be in everyone's cupboard, works every time. Not great value for money with the amount and size you get but it lasts a long time. Too much packaging for something this small, that's the only reason for 4 stars.
