Clip-in hair beads come in packs of 10 and measure about 12mm in diameter when they're completely closed. They are made of plastic and snap into place. There are little teeth (spikes) on the inside of the beads to hold them in place, so they can be used on chunks of loose hair as well as braids, twists, and dreads.
Size: 10mm x 10mm with a 7mm opening.
Brand: I Kick Shins.
Color: Pastel Rainbow. Each pack includes at two beads each in light pink, light yellow, pastel green, sky blue, and light purple.
