Gel pens tend to produce a bolder line and smudge less than other types of pen. The ink can also be produced in a much wider range of colors and this can include fluorescent, metallic and glittery effects which can work well on darker paper. The size of the nib on a gel pen can vary from around 0.18mm to 1.5mm and the advantages that they provide make them popular with a range of professions. This can include teachers, with the bold lines and vibrant color showing up well when marking papers and also graphic artists with the range of colors suiting them well. However they can be used by anyone and as well as being simply for writing they are also popular for art, with the colors and effects in which they can be produced making them ideal for this.
I think this is true, that anyone can now use Gel pens. You don't need to be a proffessional to use them anymore since they were invented in the 1880's. I imagine back then they were very expensive and people without any money couldn't buy them. As you know I'm a big fan of the GEL PEN. I find that somehow my cartoons are more funnier when they are drawn by GEL PENS. And having them available in so many bright and vivid colours is just an added bonus for me, you, teachers, and professional graphic designers the world over.
All hail the GEL PEN!
Here's a caricature of my son, which looks nothing like him:
