These masks are delivered without printing. When you do not have one of the two types of face mask mentioned above, it is a good idea to use reusable face masks. This type of washable face mask is made of cotton or polyester and has the advantage that it can be personalised with a logo by sublimation printing, screen printing or embroidered logo, although they are also available without printing.
