Purbeck Photo Face Masks or why don't you put your own photograph or work logo on. Words can't explain how much I love making these with 10% from each sale going towards NHS Charities. They are made of 100% Polyester with a cotton lining for comfort and come with a FREE two pack PM 2.5 filter. They are reusable and washable, (not with the filters though which should be changed daily and are available easily through Amazon). Free delivery is available in the Swanage & Wareham area.
