Fresnel Lens 4X Magnifier Pocket Wallet Credit Card Size • Ruler - Unbreakable Plastic for Home Office Classroom & Outdoor EDC Survival Kit Bushcraft (10 Pack Ruler/Magnifier - Red)

I keep one in my wallet, one by my easy chair, one on my bedstand, and one by my medicine bottles. They are great

I keep one of these in my wallet for when I need to read the fine print. It works great and after I whip it out to use, people think its a great product and want one too. I buy them in bulk because I end up giving them away to friends when they see me using mine.

They are exactly as described they work great the only thing I you know would like to see done differently would be if they were bigger a little bit bigger they were index card sized or slightly under half of page of a normal book that would be ideal size and maybe 5x instead of 4X then that would be ultimate I'd be going to pay a little bit more for them otherwise described. These are the flexible poly vynil compound flimsy and bendy. Won't shatter like the acrylic ones

Purchased for use as an emergency fire starter. Works well for that.

Great magnificent to see and also a great survival fire starter

Great little tool for reading pocket survival guides and good fo fire starting if the sun is out.

Nice, convenient little magnifyers, but 3 were cloudy in the corners making it impossible to use for reading.

These little lenses are the perfect size. I bought them as a joke (I mean, a magnifying lens, AND a 3" ruler?), never imagining that they would actually perform as advertised. I was totally surprised. When they came in, my son asked what they were for. I stuttered a bit, but finally said, "Fire starters?". He gave me a skeptical look, but, it was a sunny day, so he went outside to try it. Imagine my surprise when he came back in less than a minute later with a hole burned through his homework. Oops. They work. I gave them out to some of my friends, who really appreciate the portable size and magnifying ability. I didn't even confess my attempt at a humorous joke. But, I did keep 3 for myself (one in my purse, one in the glovebox, and one as a book mark). I still think they could make a hilarious gift, but they just function too well to be a joke.
