Red/Black Stranded Magnet Wire (10m/32.8ft)-- 0.15mm Strand Thickness
This is the best magnet wire we've ever seen. Period. It's so thin you can run it anywhere: between, under, over, and around anything. Between bricks. Through impossibly tiny holes. It has just the right amount of flex, and the red and black strand coloring makes it easy to hook up LEDs.
The wire is sold in 10m (32.8ft) reels of twisted red/black strands. Each strand is 0.15mm in diameter- that's just a little thicker than the average human hair. We told you it was thin!
