Missed this when it was on Kickstarter. It’s proper pen geekery. it’s an aluminium body for the Hi-Tec-C pen cartridge.
The Hi-Tec-C is my favorite super-fine pen. And loads of other people seem to have a thing for them too.
Not sure I could justify the $99 price tag, but it’s the kind of thing that in a moment of drunken e-commerce stupidity I could conceivably find falling through the letterbox. If you’re feeling flush they’re fully funded and you buy one from CW&T SHOP.
