I-N-C Optimus 4 Felt Tip Fine Point Pens 3 Black/3 Blue - No Bleed Ink These are my favorite pens ever, I order them specifically and refuse to use any other pen. They write so clean, reminiscent of a felt-tipped sharpie, but they don't bleed through paper like one of those. The ink does take a second to try, I occasionally get little imprints of my written letters on my hand when I touch the paper too soon after writing, but that's not a big deal as it easily washes off and doesn't transfer from my hand to other surfaces. These pens are not like the ball-points that leave what I call "ink boogers" - those unsightly globs of ink that smear and make any handwriting look messy. I'll never buy another pen, the Optimus is the one for me!
