TIESOME Fresnel Lens, 5 Pieces 3X Full Page Magnifier Lenses Plastic Magnifying Sheet Magnifier Lenses for Reading Small Prints or Fire Starter 7.09 x 4.72 Inch (8.5 x 5.5 cm)

I always pop one of these in with a survival kit. With effort they will start a fire on a bright sunny day and can be used for reading small print.

albeit these are smaller than I have purchased before, they are handy to keep in your wallet. I gave my last lot away to friends who had difficulty in reading a menu when out. I wonder how long these will last

Smaller than I expected. Good to keep in my bag when shopping though

As a middle aged man, your eyesight goes. Very handy to have a credit card size magnifier in your wallet.

These are just the right size for reading a book and magnify very well. There are also plenty in the pack so they will last a good time.

I am very pleased with this item. Magnifiers are a great help when reading books or magazines, anything. They work very well.

Although these little maginifying lenses are useful and I suppose that they could be kept in a purse or in your pocket, I prefer larger lenses. I prefer the whole-page magnifiers that are available. Still, these make handy little bookmarks with a built in use as well.

This is a cheap product, but although the size is handy, the magnification is pretty poor.
