Could someone please recommend a pen to me that doesn't get blotchy at only a 3rd of its life use? This cocksucker pen keeps doing this! 
I'm using a TUL 1.0 mm now, and I was under the impression that this was a premium pen.

As a cartoonist, I use technical pens of different nib sizes.
I also sometimes use these pens when writing in birthday or Christmas cards, because I've become so used to them.

But I caution you: don't invest in these if you like pressing hard when you write or draw.
They come in a variety of sizes, as pictured.
I hate ballpoint pens, and am not a fan of pencil unless its a particular technical pencil I inherited from my biological father who was a professional artist.
But Mitsubishi UniPin Fineliners are my go to. I guess it depends what you need them for.
I will say Microns are garbage. Despite so many people talking them up.

The nib worsens from the minute you use 'em. Useless!
I assume all you want is a nice quality pen to
write with. In that case, I don't have any suggestions.
But if you draw or illustrate at all, another pen which is
fantastic is the Edding 8400 cd/dvd/bd marker-- it gives you a nice, thick line (if thats something you're going for.

Again. It all depends what you're
going for.
