Sky High is quite possibly my favorite blue ink of all time (and I've tried
many!). It's a medium, true blue, no purple or green leanings at all. Really
rich, it's got depth yet vibrancy at the same time. Life's too short to use a
boring shade of blue!
The ink flows nicely and doesn't clog the nib, or interfere with the smoothness
of the writing process. The color is darker than the "sky blue" title implies,
and comes out of the pen darker than the sample on Jet Pen's color demo page.
