K&F CONCEPT Linear Polarizing Film 7.87x11.81 inches A4 Polarized Film Sheets Optical 20x30cm for Screen Educational Physics

Didn't work exactly as hoped but have already claimed it for a different project. It will work for small scratches but does not work for big openings.

Worked great on bringing life back to Atv display.

High quality sheet. I wasn't sure it would work but this worked perfectly for what I needed it for! Easy to cut to fit and fixed my projector after the polarizing film got burnt. Plenty of material to mess around with in case of mistakes and a good price.

These are great for polarizing lights, though not very durable when being taped and crumpled around the edges over and over. After mine ripped, I ended up buying a set from Selens that's non-adhesive and that's been lasting me a lot longer.

It does exactly what it seys

I bought this to refresh my dash display on my e90 and it worked really well. Please note that you will have to place film in front of dash and adjust it with your hands to get the perfect visual before cutting. Once you get the position, make the cut in that same position otherwise you will be wasting film.

The polarizing sheet was comparatively priced, manufactured well and worked very well with the experiments I wanted it for. the package surprised me with a free gift I did not expect to help keep it clean and keep it clear. I cannot see it being better for what I needed and expected

Good material. Not flexible. And Definitely not for glasses.

I used these on overhead projectors in a theatre performance. They created the effect just as I wanted and the quality of the film was good for my use.

Bought to change my digital watch display to negative. Comes with a adhesive backing and worked for what i needed

Ce sont de vrai filtre polarisé, j'avais acheté un filtre d'un autre vendeur moins cher sur amazon qui ne fonctionnait pas. Pour vous assurez qu'il fonctionne: tournez de 90 degré une feuille par rapport a l'autre elle deviendra noir. Celle-ci réussi le test ! Merci pour votre produit de qualité bien emballer. Je suis très satisfait

Nous avons longuement chercher une solution car le filtre polarisant de notre afficheur de véhicule avait fondu avec la chaleur, nous avons finalement trouvé ce filtre polarisant qui a réglé notre problème à moindre frais... Il pourra également servir pour d'autres fois au besoin. C'est un bon article que je recommande. Merci beaucoup

All you need in one package. Used it on several devices to improve and/or later the display readability. Testen other suppliers, but this set is bybfar the best.
