  • Very good Freshnel lens magnifiers

    Very interesting Fresnel lens based magnifiers that can be used for solving reading problems and lots of interesting experiments.
    The magnifiers are very thin and actually work. You can carry them easily in a wallet since they are thinner than a standard credit card.


    No Cons - Maybe DX should also offer a larger sized version A4+ for interesting sun collection and projection experiments.


    You can use one of them in emergency situations to get fire from the sun!


    A great buy at this price!
