These are a new (to me) design, called “Longwood Click Pens”. Aptly named, because they’re a decent size, and the single-barrel construction really shows off the wood. And they’re the only “click”-style pen I’ve encountered, so that’s refreshing too.
Woods are (l-r) Zebrawood (2), Pink Ivory, Walnut, Paduak, Cherry, Lacewood.
