"The best protective shields we have seen!" "Thank you for making me feel safe to return to work again" "The first protective shields with style and comfort in mind!" Bluestone is proud to roll out our first ever Face Shield line, now a fashion accessory as well. Designed with style and comfort in mind our Hard Lens Clear Shield has quickly become a favorite of the health and service industry and very important as a shield for all. Use it at work or as an added social distancing protection. Protects from air droplets.
