These plastic applicator cones (carrot bags) are extremely soft on the hands. You can do your artwork for hours and hours without feeling any strain on your hands or fingers. They are also reusable. Just wash out and reuse. To use, snip a fine hole (the size of a pin hole) at the tip of the cone and pour henna into the back of the cone with a spoon. The back opening can be secured with a rubber band.
