For those of you who signed up to the Kickstarter campaign for the Namisu 'nexus' (and probably more so for those who didn't!), it appears Namisu.com are now co-operating with Massdrop to sell a modified version of the pen - now rebranded the 'Orion'.
According to the Massdrop page (https://www.massdrop...uy/namisu-orion), the pen is slightly shorter, with fewer threads on the pen cap, and redesigned to allow the cap to post. Nib options have also been changed (EF, F and B instead of F, M and B in the Kickstarter campaign), which I think is a smart move. Oh, and there are fewer, shallower grooves at the gripping point of the pen, to provide a more comfortable writing experience (though I've had no complaints, personally, with the original design).
The Kickstarter campaign for this pen was pretty shambolic, on a number of levels - poor communication, supply delays which led to delivery delays, the list goes on... but the pen itself was (and is) pretty nice. And the price on Massdrop is pretty competitive too!
I'm not up for another Namisu pen (no complaints, just don't need 2) - but thought I'd mention it here for anyone who missed out.
