These aluminium nose wires are bendable to fit the shape of your nose. You can slip them in the pocket at the top of your mask to ensure a snug fit and to reduce eye-wear fog. They also feature an iron-on coating on one side. Personally, I prefer to slip them in a little pocket at the top of my mask and then take them out for washing.
DISCLAIMER:
These wires are supplied so that you can make simple face coverings for you and your friends/family. No medical research has been conducted in the decision to sell this product. Always consult Government guidelines with regards to best practice safety measures.
