Credit Card size pocket magnifier.
3.5X Magnifier is .7mm (9/32") thick! A tad smaller than a regular credit card.
We TESTED and Approve that this product WILL create an ember to start a fire using FULL sunlight.
Everyone should have one of these simple magnifiers in their wallet, purse, pocket, or bag as an easy (and cheap) last chance fire starter. Or, to help read that Fine print.
