Review: These are my favorite pens for writing - These are my favorite pens for writing, and turquoise is my favorite color. I am so glad that Pentel has made these available in a one color pack! Now I don't have to buy a pack with just one or two of the color I am looking for and try to find a use for the other colors. These pens are comfortable to hold and write very smoothly. They are a pleasure to write with! I would use them for everything except for the fact that they are not archival. If you spill water on your paper, the ink will run significantly. I don't use them to write checks. Other than that, I am a happy customer! And I thank Pentel for making them available like this. I actually requested it a couple of years back, so I like to think they did this for me! And just so you know, sky blue = turquoise!
Review: Lefty Favorite - I've been using Energel RTX 0.7mm (METAL TIP) liquid gel ink pens and replacements for years - very fluid writing experience, dries fast and NEVER leaves lefties covered in ink. This is also my very favorite color - could only find a good deal on a whole box - hope they will provide reasonable ink refills in time. This color is DIFFERENT than either the turquoise or blue - Sky Blue is the Goldilocks version. Please note that if you want a smooth writing experience, be very careful to ONLY purchase the METAL TIP version (not the other one not so lefty friendly like this one)… This is the ONLY pen type I ever buy, and I keep them stocked for working from home (a box of refills lasts a good long time too) - when you can find them. Note: Each refill has a plastic-dipped tip to help them from drying out.

### ⭐⭐⭐⭐⭐ Great pen - flows well, doesn't smear and beautiful color ink.
*by S***E on August 12, 2016*

Just love these pens. First bought one at Staples in the summer of 2015 when they promoted them at the register. Since then I had been unable to find this color. I was delighted to find them here. The ink flows beautifully and doesn't smear. Very happy and will be purchasing again.
