Copper Foil Tape - Conductive Adhesive - 21 Yards - Ideal For EMI Shielding, Guitar Repairs, Soldering Jewelries, Electrical Repairs, Grounding, Stained Glass & DIY Home Improvement

Its copper tape. What more can I say. The adhesive on the back is conductive so when you stick pieces together they are electrically connected. I use this stuff to line single coil pickup cavities. Once grounded it reduces noise.

The foil is fine. The adhesive is, at best, sporadically conductive. I used this for shielding a guitar (strat) control/pickup cavity. Some strips of tape conducted fairly well but others were poor conductors (checked with ohm meter). There is a very simple solution though - just pull out your trusty old soldering iron (you must have one otherwise you wouldn't be doing this) and put a drop of solder between each adjacent strip. Don't forget the short strips between pickups. It takes about a minute to do this. Truth be told, I used to do the same thing with StewMac copper foil tape anyway, just to be on the safe side.

I just bought it for decorative purposes. It's nice and bright, and the foil is thin enough to use almost like gold leaf (copper leaf, I guess). It was a coppery Christmas. 😆

This tape was highly effective in grounding my wall when I was protecting my family against the four smart meters mounted outside my condo unit. It was very easy to use.

The listing is really good and descriptive. Shipping was prompt and the product arrived intact, nicely wrapped. Good seller, highly recommend, will be returning when I need more !

Worked great, have seen less snails overall this year, and only 2 on my garden (didn't go completely around it with the tape)

Excellent universal useful product. It's about time an invention that provides a diversity of mechanical and electrical uses.

I was very happy with the seller and the product. I would highly recommend.
