Let me start by saying that these are beginners chisels. These are cheap for a reason. Keep that in mind. Yes they do work as intended, and yes you can get very nice results. But the overall quality is only medium at best. They feature a solid wood handle with a Tungsten chisel blade epoxied in. Also – The 0.1mm scriber is especially brittle. I have personally broken 2 tips by flexing the blade (once on purpose). But as long as you are careful, it will put down a nice line.
