How Do They Work?

Did you know that the secret to the warmth produced by Flexeze Hand Warmers lies in a cool chemical reaction? That's right, these nifty warmers start working their magic as soon as they're exposed to air.

Let's break it down and see what's happening under the hood. Iron and Oxygen are the dynamic duo that get things started, rusting away to produce a lovely warmth that'll have your hands feeling toasty in no time. But that's not all - salt jumps in as a catalyst to speed up the reaction, while activated carbon acts like the charcoal in your BBQ, dispersing the heat evenly throughout the Hand Warmer.

And let's not forget about vermiculite! This little hero works hard to insulate the reaction inside the Hand Warmer, so the warmth lasts even longer. And to keep everything in tip-top shape, each Hand Warmer comes in a handy air-sealed packet that keeps the moisture inside.

So, there you have it - the science behind the magic of Flexeze Hand Warmers. Stay warm out there!
