Small size, great product
Style: Face Stick, Size: 0.45 Ounce (Pack of 1)
Great product, just wish I had read the description better because this stick is TINY. On the flip side, its easy to carry around and doesn't gulf my baby's face.

This is one of the best sunscreens I’ve tried. It’s great for both your skin and the environment, and it actually works. The compact size fits perfectly in a pocket or purse, and I love the it rubs on to apply easily , it makes applying it super easy. Definitely a must have.

Favorite sunblock to travel with. Appreciate the simplicity of it, and the fact that it rolls on and rubs in smooth. Of course the iconic scent is also a plus.
