Pack of 50 disposable surgical face masks for $29.99 + $4.99 shipping at Once-it. One of the cheapest I've seen disposable masks in a bulk pack like this selling for. 1-3 day dispatch in case you need them quickly. Good for keeping a couple in your home/car or for when your reusable face masks are in the wash or if you don't feel comfortable using reusable cloth face masks.
