Here are some of the pens in my stash:
Stabilo Point 88 – it’s nice for drawing with, but it doesn’t have a lot of personality. If that makes sense..
Uniball Jetstream – a nice retractable ball point pen, nothing fancy. Usually lives on my desk for taking notes etc.
Stabilo Pen 68 – I really like these for colouring sketches and stuff. They have a nice felt tip and come in lots of colours!
Lamy Safari – sometimes only a fountain pen will do and this is a nice one! Plus it’s not too expensive.
Staedtler triplus color – also nice for colouring sketches, but not quite as nice as the Stabilo.
Pilot Acroball – another decent ball point pen.
Preppy Fountain Pen – this is a cheap fountain pen and you can tell when you use it. But it’s PINK and that makes it all ok.
Pentel HyperG – ok, I’ll be honest, I mainly got this for the colour, purple! But it is a nice pen as well. I actually like it so much I got some refills for it!
Copic Sketch Marker – I don’t use these that much, but it’s great for arty sketching or colouring in sketches. Although it is a quite smelly pen. Definitely don’t want to use that for too long at a time..
Faber Castell Pitt B – this is also nice for colouring, and you can use it on its own. It has a longish, almost brush-like, felt tip. It comes in a fairly big range of colours but the colours are slightly more muted than the Stabilo 68 or the Staedtler.
Pentel Sign Pen – another felt tip, but more rigid than the others. It’s nice to colour/sketch with, but it’s even better to write with. The name kinda gives it away, right? Comes in several colours too.
Uniball Signo Gel Grip – this is my favourite pen by far! I’ve been using it for years. I have several all over the place: in bags, my desk, with other pens etc. It’s a ball point pen, but it feels very inky and you can vary the size of the line. And it’s waterproof which is good because it means I can use it with watercolour washes. :-)
Sharpie Mini – everyone needs a Sharpie, right? To be honest, the reason I got the Mini version is that I wanted green and orange and they were in this Mini set which was also cheaper. Win-win.
Uni Posca – this will write on pretty much anything, which is very useful! And it’s fairly opaque too.
Uniball Signo – not as opaque as the Posca, but it’s nice for adding white highlights to watercolours for example.
And honourable mention for my tablet/phone stylus. Sometimes it’s just easier to use something pen like on those devices. It feels awkward to draw or write directly with my finger, but with a stylus it’s like using a pen or pencil.
