Thinkbaby and Thinksport sunscreen sticks come in an 18.4g stick made of environmentally friendly packaging that does not contain BPA, vinyl, or phthalates. The packaging and contents are environmentally safe. Each stick is marked with an expiration date.
Note: The base formulations of Thinksport and Thinkbaby sunscreens are identical. They set out to make the most effective safe sunscreen possible. It didn't make sense to make one safe for babies, and a harmful version for adults.
