Therwen 12 Inch x 10 ft Copper Mesh Screen 40 Pure Copper Mesh Roll Wire Fabric for Grounding Dense Filter Screen Woven Crafts Window Protection

I unrolled about a foot, put it on my bed connected to a grounding rod outside so that I can ground my body while I sleep and work at my computer. High quality.

this light and easy to use product is excellent. I cut strips of it to surround the patches of vegetable seedlings that snails and slugs like to nibble.I pin down the strips of copper mesh with short thin twigs of wood. Result? NO nibbles of new vegetable seedlings. Because I do not like using any poisons on my plants these copper strips are very effective. Of course it will not deter a flying critter but by that time my cauliflower were away to a great start with not a single nibble.It does not kill the snails nor the slugs but the copper does deter them from sliding over the copper. This year I am also using it around flower seedlings and once again a barrier of this copper mesh has resulted in no nibbling of the flower seedlings either. So the product is a winner for me

I purchased to make grounding mats. It is pure copper screen. Works great in my application.
