FOR ANYONE WHO IS A DRAFTSMAN BY TRADE, THIS PRODUCT IS VERY FORGIVING. SURE YOUR GOING TO HAVE DRIPS (HICKYDOOS) BUT ONCE YOU GET THE HANG OF USING THIS INK, YOU WILL FIND THE IMAGES YOU CREATED ARE SHARP, AND WELL DEFINED. IT LENDS ITSELF TO BEING A GREAT MIXED MEDIA PRODUCT AS WELL. WHEN USED WITH WATEROLORS, ACRYLIC, AND EVEN PASTALS, THE INK SETS ITSELF AND THE IMAGES REALLY POP. I ALWAYS KEEP 7 OR 8 BOTTLES ON HAND AT ALL TIMES.
