They don't bleed
Love these pens. They don't bleed through the pages of my glucose log book

Best. Pen. Ever.
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!

Favorite Pen
This is my favorite pen ever! It writes so smooth and looks nice on paper. My coworkers like them too because they go missing a lot.

BEST fine felt tip pens EVER! No smear!
I am putting all my photos in new albums so I needed nice pens to write in the photo books and these are PERFECT! I had tried some others but the ink smears. These pens dry immediately so you don’t have to worry about smearing while you write. I’m a lefty so smearing can be a big issue. The ONLY felt tip pens I have ever found to dry quickly. I’ve been using the same one for several weeks so they seem to hold up well too. Very happy!

Good pens with minor quality control issues.
Some of my favorite felt-tips on the market, and always affordable. These can admittedly be kind of hit-or-miss on quality. Every two or three packs I use, I come across a pen with a defective tip, but they write so smoothly and consistently otherwise that I keep coming back.

Easy to write pens
The pens arrived earlier than expected, and were delivered in extra packaging that made the pens original packaging in perfect condition. I love the ease of writing with these pens !!!
