SunnyPatch UV-Detecting Stickers

Pack of 2:

How does it work? These UV Stickers will darken to purple based on the UV exposure. Apply your sun screen as normal to both your skin and patch. The patch will turn clear, as the sunscreen protects it from UV rays. The patch will darken as the sunscreen wears off. Once the patch becomes purple, it's time to reapply sunscreen!

Instant, Convenient, & Effective – End the sunscreen battles with your little ones with this fun patch!. Once the SunnyPatch turns purple, it is time to reapply. And what kid doesn’t love a fun color changing sticker? Our SPF stickers prevent sunburn for the whole family!

Safe for babies, toddlers, kids & adults.
