Slots in the barrel meet slots in the cap! For the first time, we've brought the slot cap to the Spoke Pen. On the blue barrel, the slots provide a see through to the black inner sleeve for a nice two tone look. On the cap, the see through to the knurled Titanium provides a unique look. A very cool pen overall.
Note the cap does not post (attach to the back of the pen). Brian's view: In my use I usually have the pen clipped to a notebook cover and just withdraw it from the cap... so the cap is kinda like a holster. I love a click pen for quick notes and on the go use. When I'm using a pen for a longer time... like sketch ideating, etc... I like using a clipless pen (or pencil) as I tend to spin a pen in hand... for me it's just a nicer experience without a clip.
