12 Pack UV Solar Reactive Silicone Wristbands Change Color In The Sun Wrist Band Rubber Bracelet Customize

These change color in the sun. I was hoping that if I covered them in sunscreen it would help us know when we needed to reapply sunscreen. That didn't work for that.

My husband has lupus. He gets terribly sick from UV exposure. UV is more complicated than clouds and sunshine. These are great to promote awareness of exposure to UV. They are not really reusable after exposure to heavy UV.

Really fun and great reminder to wear sunscreen while they work. I was keeping one in my car and unfortunately they seem to stop reacting to sunlight after a few weeks. Wish they didn't lose reactivity.

I wore 2 at a time, sunscreen on one and the other plain to help me distinguish when to reapply sunscreen!

Well for the most part. At first they did function as intended, but over the course of a month and repeated sun exposure. They just lost their purple glow out of the blue, and became just a white bracelet.

Did not last more than a week

They change super quick which is great for kids since they don’t have much patience

They do their function very well, buy they lose the ability very fast, maybe my bad but they last for about three days only.
