What is 550 paracord? 550 paracord means that this paracord has a 550 pound breaking strength. It also wont rot and is waterproof. I've made this paracord into 2 bracelets in the colors of moss and cream and black and red and have also unbuckled them to show the reverse colors on the inside of the bracelets. The ends have been melted down using a lighter and they do buckle together with a black buckle. The sizes of these bracelets are as follows: Moss and cream- 8 inches Red and Black- 10 inches Bracelets are ready to be shipped on the next business day and arrive within 3-5 days once payment has been received. Upon checkout, please let me know which one you would like to have sent to you. if you have any questions, feel free to email me at: AmberlyLaneDesigns@gmail.com Thanks for looking.
