These paracord bracelets are made from 550 paracord. Whats that mean? it means this paracord has a 550 pound breaking strength, so its certainly strong as well as durable. I have made quite a few for myself and have gotten them in water and they are also waterproof and will not rot. They also fasten with a buckle in the back. I have three for sale and come in three different colors as shown in the images below. How does the paracord stay together and not come undone? The ends have been melted down with a lighter and how i did the two different colors was i fused them together in order to make each bracelet. A great gift these bracelets will make for anyone in your family and even friends! If you're looking for hiking jewelry, these are the ones you'll want to check out!
