I presume you are asking about the color of ink with which it writes. If you purchase a "Rolling Writer" pen which has a black case and top, it will write with black ink. If you purchase a pen which has a blue case and top, it will write with blue ink. If you purchase a pen which has a red case and top, it will write with red ink, etc. Bob

Are these non-smudge when using with a straight edge or protractor? I draw custom geometric designs for book covers and I'm tired of smudges.

It is like a rollerball gel ink so until it dries it would smudge

Has anyone found a solution to getting stuck ink to flow in these pens? Tapping them hard can work, but not always. Specifics appreciated. Thanks.

I always store mine "cap up" so the ink flows away from the tip. Never really had that problem.

Hi, this is for a box of 12 pens, correct? Thank you!

Dear Heidi, Yes, there are 12 Pens in each box.
