We do not offer exchanges on items purchased online, however, we offer Free UK returns service via Royal Mail if you would like to return an item from your order. If you are unsure of which size, colour, or style to order, we suggest that you buy several sizes/colours and return any unwanted items back to us for a refund within 30 days of your purchase. Masks are non-returnable for hygiene reasons. For more information on how to return items from your order, please please click here.
