Special marker or pen for writing in Arabic?

I'm totally new to the Rocket Arabic course, and to Arabic, and was wondering if the person drawing the numbers and letters in the writing videos is using a special marker. And do others have a particular marker or pen they like to use for writing in Arabic? ​Thanks!

The person writing the videos is using a marker with an oblique nib. These markers are used throughout the Arab world to write with nice calligraphy and in places where the Latin alphabet is predominant they're usually sold as 'left-hand calligraphy' pens or something on the lines (Latin calligraphy is usually done with straight 'italic' nibs, but lefthanders need oblique pens to achieve the same results). They reproduce the traditional lines made with reed calami.
In any case, Arabic can be written with any kind of pen (ballpoint, fineliner, etc.). I personally use oblique nibs on a fountain pen for developing a calligraphic hand, but 99% of the time I use a regular pen, and as far as I know most Arabs do as well.

Thank you so much for your answer! This helps a lot!

I’m so glad I was able to help ^^

I had never heard of lefthanded calligraphy but found a website that has a page of markers just for that, ( https://www.johnnealbooks.com/category/left-handed ), and bought some 1mm and 2mm markers where the description said "for lefthanders and Arabic".  As I write this post today's mail had come about an hour ago with my order and I've been practicing a little bit with them and all of a sudden it becomes much clearer. Having the right tool for the job really does help!

Thanks again for taking the time to answer my question!

Wow, that was fast! And I totally agree, having the right tool is sometimes the only way to really get to grips with something. By the way, the fountain pens I use are precisely the ones just above your markers. It's a small world after all!

Hope you enjoy practising Arabic even more now!
