Night Sky Constellations Face Mask: What is it? It’s a face mask with an out of this world design printed on it, letting you stay safe & stylish while you head out to the shops! About the product It’s made from polyester & double walled, letting you slip one of the included two PM2.5 filters into it. Both the filters & the mask are fully washable – we recommend washing before use, just to be sure. With ultra-soft, elasticated ear loops, this mask fits most adults & is comfortable to wear. Oh, & £1 from your purchase will go to NHS Charities Together to support NHS staff & volunteers! Why you should buy it There’s no reason that your face mask has to be as plain as a bowl of boiled cabbage. We say, bring some fashion to your face covering!
