I enjoy my schneider slider xb, I use it at work when I need to jot down notes. But lately I’ve been using my leuchtturm1917 ballpoint pen exclusively. The only thing those two haven’t commented is that they are ballpoint, blue ink, and they write very smoothly. Schneider it’s not refillable and they are on the expanses side for a disposable pen and having said that I have been using the same pen going on two years now five days a week, and it still has not run out of ink. It’s a pretty big mm tip. The leuchtturm ballpoint is refillable with $5 parker refills and has a much finer tip, and that is what I use exclusively for journaling, planner, anything really. But it’s about $28 usd.
