The tips of almost half of the markers had dried out as soon as the product arrived. However, even with half of them, you have a great variety of colors.
Also, the thickness of the line that each marker produces differs significantly from the others: some require a lot of pressure to release color and make a very thin line, while others make a thick line without much pressure. You need to get used to it and remember what each one does.
It's worth buying because you get a wide variety of colors.
