cord ends' from County Comm. They come in handy to use with zipper pulls, lanyards, and fobs, clipping onto the end strands of cord. You can use them with simple loops of paracord to quickly make zipper pulls, or add them after knot work to cover and finish the ends. Examples shown with some gaucho knot beads over paracord. The pocket knife is an Opinel #6 with carbon steel blade.
I also got a couple of rolls of Extreme Tape, but haven't put them to use yet. I've used this type of grippy wrap under turks head knots in the past, to keep the knots from sliding off of smooth bodied flashlights
They can be used to identify the contents of your bag/pack/pouch, perhaps using the glow-in-the-dark version on a zippered pouch/compartment for flashlights, orange for pocket knives, green for tools, etc... Just tell a friend, family member, or stranger to look for the 'red' cord end zippered pouch to quickly find the first aid kit if needed, etc...
I tested the glow-in-the-dark cord end on the nightstand, and 8 hours after turning out the lights, I was still able to see the dim glow of the cord end with my dark adjusted eyes.
