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

Product was everything that is advertised and still so much more impressive once in hand

Yes its an actual piece of copper woven into the form of a screen. Very useful for whatever your neesd are.

Works for my project.

Worked fine just rolled it up to use for a filter

Easy to cut and durable

Wrapped it over my WiFi Extender router, after I learned of potential negative health effects, and it reduced my signal by 50%. It reduced it enough with a single layer of wrapping (gorilla taped it closed) that the back of my house (baby nursery) has only one bar of signal. I also made a grounding mat out of remaining material by gorilla taping the rough edges, gorilla taping the copper extension cord wire to one end and wrapping the other end around a galvanized steel pole inserted into the ground a foot or so deep. I only stripped the ends of extension cord.

Awesome

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

About this to put inside of my mask and it works great.

Very fine mesh screen.
