Paracord survival bracelets are pretty common these days, so much so that you can even buy them online. I’ve seen them in all variations at gun shops and local gun shows, but they always seemed pretty overpriced. Sure you can make your own for much much cheaper, but if you’re too lazy or don’t feel like you’ll be able to braid your own, you can find paracord bracelets online at pretty darn afforable prices.
If you do feel inclined to try and braid your own bracelets, paracord is pretty cheap as well.
