"The write way to roll". Use the Rawl Pen to roll perfect cones the easy way. Just put the filter tip in the end, line up the paper and roll it tightly, lick and stick. Hold the cone by the tip and pull out the Rawl Pen and you have a cone that is ready to be filled. A packing tool is included. And if you want to mark the tip (or something else) the pen is equipped with plant-based ink.
