Okay come descrizione

I used it to shield a guitar cavity and it was great.

Passed all the impedance tests and stuck really nice with no effort into my pickup cavities on my guitar. You get loads of sheets I only used 2 in pack so have lots left for future shielding projects

Ottimo prodotto rispetta ciò che cercavo, grazie mille

great product works very well for faraday cage as tested. No signal in or out and voltage in cage upon energy release not detectable level. two thumbs up!

J’ai espéré faire une vraie barrière aux limaces de mon petit jardin.Hélas! Cela ne fonctionne pas

Pratici e comodi per l’utilizzo. Qualità prezzo ottima. Consegna veloce

I use copper foil on all my guitars, as an EMF shielding, in preference to the paint on version. It's my personal choice as I don't have much confidence in the other alternative. It's also very useful if you are using imported custom made Strat style pickguards from the US, as some don't come with the shielding applied on the rear face. Size wise, it's almost A4 size. The packaging is pretty non descriptive, with no manufacturer details, just a couple of small stuck on labels on the packet. It is sticky, and can be frustrating to use, by anyone who hasn't tried it. Take my advice, and do not attempt to cut elaborate shapes that match your guitars cavities. It will curl up, stick to itself and other parts you don't want it too. Cut strips approx 1 inch wide, and apply by peeling just a small part of the backing, and apply to surface from bottom of strip using finger if possible, peel and feed strip to end position and cut with a small craft knife. Repeat till cavity completely covered. Remember it doesn't have to look pretty but be functional. And be patient.
