I acquired a Whip via trade a few days ago. Its one if the Dr. Blood ones from a few years ago. The only thing that could make it better would be if it had some weight to it, lol. Im having trouble staying steady with it as I am so used to lining with heavy coils. But, its really cool, Trouble and glitch free lining and shading all week. I can drag lines in any direction like a pen instead of pushing all the lines which is pretty amazing! Ill buy another.
