Gun Metal Adjustable Shackle
If you can imagine "black chrome", this is what they look like. Make sure you watch the video to get a really good view of the color.
Shackle are a great way to add a little more flair to your paracord projects. And these shackles are awesome. These shackles come with an adjuster bar. The adjuster bar allows you to make the bracelet up to 1" smaller or larger. The shackles can also be used if needed in survival situations.
