Our uniform-size stylish face mask is not a personal protective device against infections, it also does not conform to the FFP standard, and the mask is not a medical device. But it has an internal hole for adding filter materials or something like that. With stretchy ear loops and a small chin clove, this mask made of simple jersey fits almost perfectly on any face shape and with or without a bold print on the front is a real eye-catcher. Made in Bangladesh.
