Best Glide ASE Credit Card Size Fresnel Lens Fire Starter and Magnifier Lenses (3 Pack - Red)

One of the smartest Survival Tools to always have around. 101+ Uses! Besides being a superior magnifying tool these make excellent Fire Starters, scoops for pills and powders. You can even cut cheese and soft foods with it! Everybody should have a 3 Pack of these!

These are just nice to have around. They do a great job as magnifiers, easy to keep in a wallet/purse to have at all times. Cheap enough where you can buy lots, and have them all over the house/shop/garage, wherever you sometimes need one, always at hand.

Great product. Came quickly and was at the bottom of the box with another order. These things are so slim you really have to be careful that they don't get lost in the shuffle if they are in with another order. All three of the lenses came without any deformities or real aberrations. A Fresnel lens is a flat lens made of a number of concentric rings with each ring slightly angled to focus the light to a certain spot. This allows for good magnification without the bulk of a traditional magnifying lens (if you already knew all this I apologize, but I certainly didn't). Anyway, these lenses are just as advertised, very slim, very strong, and very flexible. The flexibility is great so that you don't have to worry about cracking them very easily. The magnification does seem to be right around 4x like they say. The protective sleeves come with some nice inspirational quotes from some great minds and you can see the magnification in my photo. Sorry it's a little blurry in the background but the depth of field on my phone at that distance isn't so great. Anyway you get the idea of the magnification. You can also see the distortion at full magnification as the letters bend a bit on the outsides. So, I bought these as just an extra backup way to make fire in my emergency/bug out bags. It's nice to have something that doesn't rely on any fuel or that needs to stay dry (lighters and matches). I haven't tried to start a fire with them yet as it has been overcast since I got them (of course, right?!) but once the sun comes out I'll give it a shot and update. I'm pretty confident that on a full sun day you could start some tinder smoking pretty quickly. I'll find out.

Compact. Easy to carry. Good quality. They work as designed.

I put one of these in my wallet because I don't want to carry my reading glasses when I got out to eat. Very handy to read menus in the dark restaurants with small font.

It’s a fresnel lens.

I compared these to the 3X ones I have and they are same power. So, you're paying for 3 of these when you can get a pack of 12 for the same price but without the tacticool "survival" printed vinyl sleeves.

they are very small (wallet sized) they actually burn stuff, they’re a little flimsy, the price is pretty good
