For a small price, this set offers everything you need to start well. 4 feather shapes suitable for 2 pens (2 pens are convenient to work simultaneously with two different colors), several ink colors, easy writing on any type of paper, a booklet with different alphabets model and a marked slip lines that can serve as a guide, this is pretty good. A council after inserting a cartridge: lightly press the pen and its back with two fingers to bring the ink. My only question is: what about the ink refills? Where to find them? The "tips" Are Standard? I also regret the absence of a broader round pen than the one provided. But the value is excellent.
