These cuffs are fit for royalty! Crown shaped hair cuffs come in packs of 10 and measure about 15 mm in diameter when they're completely closed. They're easily bendable, though, so you can squeeze them onto larger dreads if you leave a small gap in the back, or you can double up two at a time and make one really big cuff instead.
Size: 15mm x 10mm.
Brand: I Kick Shins.
