I was looking forward to trying the green black version of the Uni-ball Signo DX, but I was disappointed to find that JetPens only offered it in 0.38mm, and not in 0.28mm, which I had been wanting to try as well.
Despite that issue, this is still an excellent pen, and will likely end up on my list of top five pens in the future. I don't have much to say about the way this pen writes that I didn't say in my earlier review of the lime green version, other than to say that I have experienced no problems at all - it writes very smoothly, with a delightfully fine line.
I love the colour, which is the perfect shade of deep green, with just enough black in it to make it acceptable in any setting and just enough green in it to make it stand out (the photograph does not do this colour justice). I have liked all of the combination colours that I have tried (such as blue black and lavender black), but, given that green is my favourite colour, this green black is probably the best yet.
