The malleable nose clip deforms easily so that a good fit can be formed around the bridge of the nose. Continuous or exaggerated deformation will eventually cause failure in the metal – it will snap.
Once a good fit has been found, it is best to maintain the shape, rather than folding it flat when storing it or when not in use.
If the nose clip breaks, all you have to do is send a picture of it, indicating size, model and address details to firstname.lastname@example.org and we will send a replacement shell FOC. There is a small shipping charge which is charged at cost and dependent on country location.
