Homemade survival bracelets! Select options for a custom bracelet. Pre-made bracelets are approximately 6" so that they fit most wrists, but if not, they can be attached to your favorite backpack! These are made with high-quality paracord (5-10') wrapped around a good length of jute cord (fire starter), and bracelets are fastened with a multi-function buckle (compass, fire starter, and whistle).
