Go on amazon and look for it but be careful I just got mine today and I accidentally bought poly core. It's the same type of stuff but the yarns of the inter strands are thinner and harder to get apart. Oh yeah buy 1000 ft of black you can find the 1000 ft spools for around 30-45 bucks. Hope this helped. Keep on keeping on. P.s. Paracord planet on Amazon is a good place to start
