Hear that sizzle? That's the sound of your little beachgoer’s skin under the hot sun. SunnyPatch was designed as the leading UV detection sticker. When the sun comes out to play, this little patch will save the day. It tells you when it’s time to reapply sunscreen! HOW THIS SUN DETECTION PATCH WORKS Each SunPatch sticker is crafted with a natural, UV-sensitive ink that turns purple when it's time to reapply sunblock. Placing one of these sunscreen reminder stickers on your kiddo’s skin will help prevent sunburns and sun damage! We’ve used medical-grade, water-resistant adhesive so this sun-safety patch stays put. Peel off, replace sunscreen, and slap on a new sticker! These sunscreen dots are perfect for babies, kids, and even older family members who still think SPF is optional! PACKAGING These retail-only packs come with 27 individual patches in assorted colors (not available online). Pre-packed retail display boxes can be opened, folded, and displayed.
