{Summary}
About 2.5X magnification. 0.5mm thick (thin enough to be cut with a knife), postcard-size, about 4 X 5 inches (more precisely, 35 X 95mm).

The 'lenses' are cut into the plastic as micro-grooves (very clever), as invented by Augustin-Jean Fresnel (pronounced "Fren-nel") in about 1818, and originally used as the 'magnifiers' around the lights of lighthouses. To use a Fresnel magnifier you must hold it a few inches above the object, they do not work by resting on top of the object.

This is a very low value item. We have a minimum order charge of 7.50 (6.25 + VAT). Is this the only item you require? You may wish to buy more than one, or add some other items to the order.

{Technical}
Magnification / lens size in mm: About 2.5X, credit-card-size.

Field of view: vertically, about a third of a page (of a paperback book); horizontally, nearly the width of a page (about two newspaper columns).

Lens material: plastic

Origin / brand: imported by us from China.

Presentation: it comes in its own clear plastic wallet.

{Applications / Quality}
Generally, these are flat (well, not 100% two-dimensional, but very thin), the thinnest can be cut with a modelling knife if you want to make it smaller; they can fit into credit card holder or be used as a book mark.

Specifically, small enough to slip into a bag or pocket or use as a bookmark. Can be cut with a knife, e.g. to fit over a sat-nav. or smartphone display (you'd have to make yourself a cardboard 'stand' to keep it at the right distance).

{Alternatives}
Conventional reading magnifiers with handles are better in optical quality click here. And small (pocket-size) general purpose folding magnifiers are more powerful. click here.
