The Folia Gel Pens are normal roller ball gel pens. Some of them go smoothly over the paper and some of them are scratching. The colors are very pretty but when I got my package, in my package 2 were damaged when I got them (there was never color coming out) and they are also filled very different. Therefore I’m not sure if I should recommend them. I think I will try other ones instead.
+ 30 colors available
– some in the package are nearly always damaged
– fill level is very different
– are empty very fast
