The first thing you need to know is that this kit DOES NOT come with a tone cutter/tone knife. The information on the page is off. It only comes with one sheet of some basic "sample" screentones, and an even smaller sheet of Illust Tex, ink dots/patterns that you rub onto the page and then pull the plastic off. Also, the ruler is a French Curve ruler, not a straight ruler, and there are pen holders for each type of tip, meaning there are two pen holders in total, not one. And there are two brushes, a smaller one and a larger one. It's a nice sample of supplies! However, keep in mind that it is just a sample, so expect to have to purchase more of anything you like in particular. (The screentones won't last you very long.)
