I just finished reviewing Nemosine Neutrino, Fission, and Singularity these past few days. Overall, my experience with Nemosine pens is pretty good. I like that they all have very simple designs, and that they have pretty color options for each model. In terms of look and feel, I think my favorite is the Neutrino. It’s slim, doesn’t post, and the weight is just right. Even if the body is metal, the size makes the weight just right for me.
The nib is pretty standard across all three, even though Neutrino has a #5 nib and the other two have #6 nibs. Here’s another look at the writing sample of different nibs:
I enjoyed the broad nib most, and the 1.1mm nib next. The broad nibs that I tried wrote pretty well, as far as steel nibs go. They don’t require tuning or fiddling (at least not those that I tried), so these pens could be great for fountain pen newbies who just want something they can use without much fuss. I also noticed that the nibs are more reliable compared with similarly priced pens.
As far as entry level pens go, all these are pretty su-weet. If you’re looking to get a pen that looks good and won’t cost too much, any one of these would be a great option.
All these pens are available at Everything Calligraphy (obviously one of my favorite online shops).
