Chakoner in white. This plastic heart contains CHAKONER, a powdered chalk for drawing a fine line every time. The powdered chalk dispenses from a rotating serrated wheel located at the bottom of the heart container. No more sharpening and your hands will stay clean. A real must if you do any kind of sewing. Remove gold seal and run fingers along serrated edge until it rotates. Remove plastic bush on top to refill Chakoner.These are great to use, and they won't break or crack!
