It'd been a minute since I bought a new pen, and I've always wanted to try a vacuum fill pen so I finally pulled the trigger. The pen writes so well straight out of the box but that's always been my experience with TWSBI pens. The kon-peki ink is a nice beautiful blue that also seems to dry fairly quickly which is nice because I'm a lefty and it's impossible for me to write without making a mess lol.
It's a fine nib! It's not reaaallly as fine as I'd prefer (I'm weird and kinda like scratchy pens lol) but it's still good!
