The bristles are thick and have a rubber type coating
THE CONCEPT IS GOOD BUT THIS BRUSH DOES NOT WORK WELL. THE IRON DOES NOT STRAIGHTEN ENTIRELY. IT LEAVES MARKS ON THE HAIR AND LEAVES THE ENDS LOOKING MATTED.
The simply straight Ceramic Straightening Brush is really easy to use. Just use it like you would a brush. Leaves my hair so soft and shiny. I love it.wonderfully straight price is not expensive.
