2 Pieces 99.9% Pure Copper Sheet, 4" x 4",18 Gauge(1mm) Thickness, Film Attached Copper Plate, Great for Jewelry, Crafts, modelers

We bought these to place in the base of our bird baths so that the water would be better filtered. They are absolutely great for this purpose, easy to clean and maintain and they do not disrupt the birds ;-)

I’ve been using the 99.9% copper plates for grounding, and I’ve experienced remarkable relief from discomfort caused by non-ionizing radiation. After placing these plates under my work area and grounding them properly, I noticed a significant reduction in pain in my arm and breast, which had been troubling me for a long time due to a semiconductor implant. The swelling under my arm, although still present, has decreased noticeably.The quality of these plates is excellent, and they work effectively when used for grounding and shielding purposes. I’ve even covered my mouse with copper tape and grounded it using the plates, which enhanced the effect. Since adding these to my setup, I feel much more protected and comfortable.I’m considering adding two more plates to my setup because the results so far have been so positive. If you’re dealing with similar issues or just want reliable grounding for other uses, I highly recommend giving these a try! They’ve truly been a game-changer for me.

One of the post clamps on my car battery wasn't fitting tight enough so sometimes the car wouldn't start. Even with the clamp tightened all the way it could easily slip off. I'm not sure why, but over time the copper gets thinner. Rather than go through the hassle and expense of replacing the battery post clamp, I decided to wrap a thin sheet of copper around the battery post as a shim. I ordered the 4"x4" copper sheets and cut out a 2"x.5" strip. I wrapped this around the battery post. I opened up the clamp wider, fit it over the copper strip and the battery post, and then tightened up the clamp. It is very solid now and won't come off without loosening the connector. I'm very pleased.

These are great copper sheets! My son used them for his science fair project making copper acetate crystals. They worked great for that! They come well protected and seem to be great value for the price.

As described.

I'm satisfied and pleased with our agreement but I have four sides only one side was scratched you going to have more complaints about that though because it's the way you packing it copper scratches it need to be wrapped single piece individual piece wrapped and then placed in styrofoam, then put in a bag or box 🌟🌟🌟🌟. Thank you again. These do look a whole lot better one of them is beautiful the other one it has one scratch on one side but it's cool everythings good.☺️

Good packaging, consistent sizing.

So far no complaints a good thick plates,should work great for the anodes on my copper plating
