Dont worry I cleaned them with lens cleaner and let them dry before repackaging them. I work in an emergency department in the US and thought how badly needed more of these N95s were needed so I went ahead and ordered the muffs with the intention of obtaining some hard to find PPE for my local hospital. It was hard to get the originals off but once I did, these just stick right on. Other than this slight defect, good sound + smart easy to use interface and sturdy build. Its also strong enough to let you really tighten it down. Great shoes, Crocs are consistently comfortable. Try as I might I can?t get them to fit right so off to the trash they go Unica pecca è che si possono creare password solo con i numeri 1, 2, 3, 4 da inserire nell?ordine preferito, ma ci sono comunque 23 combinazioni possibili (sarebbero 24, ma la combinazione 1 2 3 4 la eviterei ??). I looked at several products before choosing, I chose this one because it offered 2 pairs at a competitive price. It was clearly a return item sent to me and was missing 2 pieces - the pieces meant to stabilize the side by side racks, so put together it was completely wobbly.
