This credit card sized Fresnel Lens can be used to start fires. Fire can be the most important thing to have in the outdoors but most people don’t carry a way to start a fire with them all the time. This Fresnel Lens is small enough to fit in your wallet or in the back of a phone case.
A Fresnel Lens works exactly like a magnifying glass so all you need is some sun light and some dry tender. Experience and know-how certainly doesn’t hurt so make sure you know how to start a fire with a Fresnel Lens!
