Super portable sunscreen
Size: 0.49 Ounce (Pack of 1)
These are awesome for keeping in a backpack, a kids sports bag, or just dropped in your pocket while traveling. I probably would want to use this as my primary sunscreen on the regular just due to size but it's amazing for reapplying during the day.

Great sunscreen!
Style: SPF 50 Stick, Size: 0.49 Ounce (Pack of 1)
Great sunscreen for babies/toddlers. It works well and it was a breeze to apply. It did take some effort to rub in. The product itself is very small, so it’s convenient to carry in your pocket or throw in a bag. But I’ve also misplaced it a few times.

Nice sunscreen!
Style: SPF 50 Stick, Size: 0.49 Ounce (Pack of 1)
My favorite toddler sunscreen! We mainly use this for my toddlers face and neck, as it’s easy application and doesn’t get all over my hands. Would definitely recommend, it’s easy to have in your diaper bag!

Good for face application, small, takes effort to rub in
Style: SPF 50 Stick, Size: 0.49 Ounce (Pack of 1)
Bought this because I thought it might make face application easier with my toddler. He definitely prefers it, mostly because he thinks it’s fun to apply and he can do it himself. But it also takes a little more effort to rub in than just the thin normal liquid copper tone baby mineral sunscreen. Gives pretty good protection though, once it’s all rubbed in! It rolls up like a deodorant stick, so you can keep it low. It’s very small, like the palm of your hand, so it’s best just to use for face. If you use it on the whole body, you’ll run out fast. It’s nice to slip into the diaper bag without it adding too much weight or worrying that it’ll open and get everywhere!
