Review on Value Pack of 3 Rolls - 7/32 inch Venture Black Backed Copper Foil by Chris Harrington

Almost no black backing. It's more of a dark gray with no permanent coverage, with lots of tiny spots that aren't black at all. Sounds like a factory problem or poor quality backing material that doesn't stick very well. In finished products, part of the underlying copper foil is visible through the "black" substrate (when using transparent or translucent glass). Otherwise it's just 1.25 mil foil like any other. Maybe I got a bad batch. Works well with opalescent glass, but any foil will do. Paying a little more for a black back and not getting a good black was a bummer when I opened the package to use it (too late to return).
