99.9% Pure Copper Wire 40 Mesh- 12.5 x 38 Dense Filter Screen Mesh

Simple test, wrap your phone then watch the signal strength drop by 1 bar. Grounding has no effect.

Good amount of copper mesh . Clean cut and nicely packaged

Good item. On time. Met my expectations. Will purchase again.

This screen appears to be of good quality, but it comes folded and stuffed into an envelope with sharp creases that will not come out. Do not buy this if you need a single, clean piece.

Was exactly if not more than I was expecting will be perfect for my project

I live on the lake and have trouble with invasive zebra mussels all over pump inlet. Wrapping with copper mesh is supposed to keep mussels away and I think it works.

Awesome

Easy to use I created a grounding/ earthing mat from the copper to put under my feet while at my computer.

Easy to cut and durable
