This is a spool of black Techflex-brand 3/8" 3:1 heat shrink (same size we typically use). The spool started off at 200 feet, and we used maybe half of it. I'd guess there's about 75 to 100 feet left. We ended up not liking it because the color was too light to be a nice "black," it is more like a dark gray.
