I bought myself a little green Christmas present in the form of the TWSBI Diamond 580 in Christmas green color ($50). The body of the pen, where the ink reservoir is, is still transparent but the cap and piston end are a lovely green color. It’s not a kelly green which I thought it might be but rather has just a hint of blue making it very unique color — like tender blue spruce maybe. The color tickles me.
I’ve owned a Diamond 540 and the 580 is pretty much identical in size, shape and weight. Since I gave my 580 away awhile ago, I can’t do a side-by-side, but to the naked eye, there is no distinct design difference. I think they just improved the materials to eliminate the cracking issue in the early 540 line.
The 580 shipped in the same cardboard outer box and clear plastic inner box that my 540 and TWSBI Mini arrived in. I like the packaging. Its pleasing to look at without feeling too over-the-top.
I ordered the 580 with an F nib and it has ended up being smoother than my previous EF nibs. I was pleasantly surprised with how smoothly it wrote and didn’t feel all that much broader than the EF.
The 580 in green is another fine product from TWSBI. If you’ve been considering adding a TWSBI to your collection, the 580 is a great option and is available in a lot of color configurations.
