Historically, Tactile Turn has stuck with the idea, "If it ain't broke, don't fix it" on the diameter of its pens. The most common request from its customers over the years was for slimmer pens (and pencils), so once the shop had more capacity, Tactile Turn made them. Updated, deeper carry milled clip.
The standard size is 5.6" in length. These work perfectly with Pilot G2 0.7 mm refills.
