Travel size products, best sunscreen out there.
Style: Original, Style: Original
Great as always but picture is misleading a bit, this is the small travel size bottle not the full size. I should have read better, still like the set nonetheless of course. Heres a picture for comparison.

Sun Bum kit a saver!!
Style: Mineral
Great little bag full of sunscreen for my grandson. Glad we had it to take it everywhere with us. A little pricey but he needs it so instead of taking bunches of bottles we had this.

Sunscreen is great, I would t recommend the chapstick
Style: Original
Sun Bum is hands down the best sunscreen I’ve ever used. It smells incredible, like a tropical vacation with that perfect coconut scent. It goes on smoothly, doesn’t leave you feeling sticky or greasy, and actually works! As long as I reapply every few hours, I don’t get burned, which is more than I can say for most other sunscreens I’ve tried. The face stick is good, goes on easily, but is a little greasy feeling. I do not like the chapstick, I can’t keep the taste of it out of my mouth and I feel like you have to put it on again and again.
