I am a self-confessed pen-a-holic. I have been for many years and I collect them. I don't really collect expensive pens - my most expensive pen is my Lamy which was about $30 almost 8 years ago and still runs like a champ. I love the color turquoise as well and when I moved in to my new office at work it was an opportunity with all the space to pull out all my pens I realized I had a LOT of green, blue, teal, and turquoise pens. I thought it would be fun to just compare the ones I like the most. All these pens were purchased by me and my comparisons are not scientific but based on personal preference.
Pilot is one of my favorite pen manufacturers because their pens always seem to write so smooth. I really like the Juice and the G-2.
Papermate came out with an Inkjoy line and while I like the standard black Inkjoy pen I have the colored inks don't seem as 'joyful' as the black one. The other thing I notice about the Inkjoy pens is if they stand in your pen jar for any length of time you may get a mess when you first write with them-a large discharge of ink....see the sample picture for an example of that.
The Zebra Sarasa Clip .5mm wrote a little scratchy which surprised me as normally .5mm pens aren't so noticeably scratchy.
A favorite of my is and always has been the Le Pen (yes I know I just wrote the the pen)...I want this line in every color. They write great, the colors are vivid and they feel nice in the hand...and they are very inexpensive.
I had a couple fat (.8mm to 1mm size) gel pens in the bunch - the AtYou Spica Glitter and the Gelly Roll "Gold". They both write well with no skipping (remember when gel pens first came out and you were lucky to write a sentence without major skipping?) I must have bought them because of the color. The Gelly Roll "Gold" is gold because of the gold flecks in the ink. The gold and the glitter both show up well on paper.
I also had a few highlighters, a Sharpie, a drawing pen, and a brush pen in the bunch. My favorites of those are the Staedtler Classic and the Pilot Frixion - the Frixion is erasable as you probably know and I like that option, especially in a planner.
So there you have it. The picture of the pens has them in order of the sample page. Only a few of the pens bled through standard, cheap, tablet paper. Most of the highlighters bled through.
My recommendations based on this sample test are the Pilot G-2, the Le Pen, the Staedtler Classic, and the Pilot Frixion Light Erasable Highlighter.
