Hi there!
I am not sure what type of mask you are wanting exactly, and these aren’t ortho themed, but I ordered my family masks from Love Your Melon, and they are great! https://loveyourmelon.com/pages/face-mask-products-collection.
LYM is a great company, and for each mask purchased, they donate a mask to the medical community. They are a beanie company that donates beanies to children with cancer and they also donate some of their profits to pediatric cancer research, so I like ordering their products and they are always great quality!
Hope this helps!
