I voted other.

I use a Parker ball point pen and a Japanese 4 color selectable erasable ball point pen.

FWIW

Why not vote for ballpoint pen?  I found 22 different types and decided to condense them all into the generic style not the individual types.

Because you cannot erase many ballpoint pens, but there are erasable ones.

That's why I chose other. I sign things that need to be permanent with my Parker, but I often write memos and other scant drawings with erasable ink pens.

FWIW

Did anyone ever say you are difficult?  I can’t possibly think of all possible poll answers in advance.  But other is fine.  That is why I always include it.

Talk about different approaches.  I just bought a box of 8 mixed color extra fine point permanent ink markers!  My husband prefers pencils, hates ink pens.

I prefer gel but I’ll use anything.

Most people I know who hate ink pens have had them rupture or leak in their shirts.

FWIW

Almost any pen can leak if given the chance.

I was really odd man out as few attorneys offices use anything but pencil when reading or reviewing docs.  My cohorts in crime used to say "here comes Ms Ego with her ink pen" as they marked docs up furiously with sticky notes and pencils.  My DH used to have his ends leak in his shirt,pockets, 90% of the time I could spray the stain with Aqua Net hair spray and t would wash right out if it was a normal ink pen.  Gel pens were trickier.
