RARE MicroMatter Zinc Foils EXTREMELY THIN .002mm / 2 microns x 3/4" x 1/2" LOT 28 pcs. Here you go! What a deal. This is a pretty cool set of foils. I literally, don't think you can buy these, this small, on the open market. These were special ordered for a working government lab. This is .002 MM thick!!!! Ridiculous. These are mounted and bound up on a rod. These may be rings, or circles. I did not take them out to figure it out. They are very sensitive. Attached power cord with this unit. Will ship international (we get very good DHL Air-Freight Rates) please ask questions. Please look at pictures.
