Combo UV-Alert Card (5pc) + Sun Tattoo UV-Alert (5)

UV-Alert Card:

A fun gadget to let your customers measure UV radiation and show them how quickly they actually need to apply sunscreen (even if it's cloudy or still early in the season). Depending on the amount of UV radiation, the UV-sensitive part of the card will turn lighter or darker in color. It can be used multiple times.

Sun Tattoo UBV-Alert:

A fun gadget to let children (or adults, of course!) measure UV radiation and show them how quickly they actually need to apply sunscreen (even if it's cloudy or early in the season). Depending on the amount of UV radiation, the tattoo will turn lighter or darker purple in the sun. If the skin is protected with sunscreen, the tattoo will remain transparent.
