There's nothing particularly special about this blue, but it's a very steadfast and dependable ink. It won't turn heads and garner complements. It's well-behaved and predictable. In my mind, I think of it as my default, professional blue. And while that might sound boring, it's also a very high complement. Each ink has a purpose, and this one fills a very specific need.
I bought a bottle of Lamy Blue from JetPens on a whim. I was intrigued by the bottle and the tape attached to the bottom, and I knew I didn't want another bottle of black ink, so blue it was!
The bottle is larger than I expected. 50 ml is the same size as my Iroshizuku ink, but the Lamy bottle is larger in order to accommodate the roll of tape on the base. As you'd expect, the bottle works great for filling pens. What more can I say? What I find interesting is the blotter tape. This is extremely handy for cleaning up a pen after filling it. The tape has two sides: an absorbent side and a water-proof side. The absorbent side does an excellent job of soaking up any ink droplets on the pen, while the water-proof side prevents the ink from soaking through to your fingers. You can clean up the pen without staining your fingers!
