Since the only difference with this Al-Star is the color, I won't spend a lot of time on the details. Check out my review of the Charged Green Al-Star from 2016. Everything holds true for this copy as well!
The Lamy Al-Star is a solid fountain pen. It's not as affordable as the Safari line, and some people enjoy the Safari line more for many great reasons, but the Al-Star hits a nice balance of design, weight, feel, and awesome colors that set it apart from the Safari. If you haven't tried out an Al-Star (or a Safari...), then I highly recommend picking up this limited edition color.
The Lamy Al-Star in Pacific Blue is $36.00 and available with an EF, F, or M nib. Remember that Lamy nibs are easy to swap out with another size as well. Each Al-Star ships with a single blue cartridge, or you can purchase a cartridge-converter separately.
Lamy Pacific Blue ink
The other half of this year's Lamy special edition combo is the Pacific Blue ink. You might have heard, but it's no secret that Pacific Blue is, in fact, the same ink as Lamy Turquoise. I don't understand why Lamy released Turquoise under a limited edition moniker instead of formulating a unique ink, but that's not the point of this review. As such, keep that in mind if you already own Lamy Turquoise! You can safely skip this ink knowing that you already have it.
