I love sticks. Convenient and no product runs.
Size: 0.47 Ounce (Pack of 1)
Purchased for my toddlers 3 - 5 years old faces. Easy to apply. Doesn’t break out or irritate skin. Prevents sun burn if you apply About 30 mins before water play or outdoor play in heat. Doesn’t bother their eyes. I like the sticks so I can smooth over face and cheeks with out the sun screen running. Good stuff.

Absolutely love!!
Size: 0.47 Ounce (Pack of 1)
By far the best baby sunscreen I’ve used! Better than Mustela sunscreen stick. This one glides on comfortably, is sheer and does not go on white at all, and smells great and the lid slides on and off easily. It’s quite durable and just the ultimate best sunscreen stick. The ingredients seem to be as safe and nontoxic as the other big brands and the price is very reasonable. Will be repurchasing.

Less chemicals than others and it works! Need to sell a larger version however!
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 0.49 Ounce (Pack of 1)
Easy application and excellent for sun protection! One of the "cleaner" ones with less chemicals, but could be cleaner. The tube is very small, so we only use this for face and use Alba Botanica for body. Last time swimming for 1.5 hours, did not burn, while friends who used other sunscreens on their faces were sunburned. Coppertone, please make a bigger tube!

Was NOT Moana themed
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 0.49 Ounce (Pack of 1)
Worked perfectly for our Disney trip. Fit well in our fanny packs. Kind of greasy, but its hard to get away from that with sunscreen. Be advised, though, it was NOT Moana. It was just a regular stick. My kids were a little disappointed.
