I love this stuff! It goes on so easy and stays on!
This stuff is great for your face! I discovered it when I went to the Bahamas, and have never used anything else.
Waterproof walkie talkies! I remember wanting to venture on my own as a teen. So my parents bought a set of walkies if we wanted to go further down the beach on our own. They are usually inexpensive and a great alternative instead of getting your phone wet!
