I am relatively new to paracording. Have done a few bracelets with compasses included. Wanting to order more cord in several different colors and some buckles,problem is I am seeing 100 ftrolls priced from 4.99to9.49. Can someone please explain the differences to me in particular it seems that cord indicating mil spec is more expensive, why is that. Most of what I will be doing will be survival bracelets, would like to make abelt or two. Any advice would be appreciated.
