I've tried a few fancy pens, but still prefer my Pilot G2 07s.
I like Pilot G2 pens but unfortunately, they have a limited shelf life as the gel ink inside dries out.
I just found this out recently when I went to get some more "new" Pilot pens from my supply closet and noticed every one of them was dried out. I bought them 7 years ago. Various websites and youtube hacks suggested putting the tips in boiling water for a while to try and revive them but that didn't work.
I had 3 boxes of black, blue, and red Pilot pens so I guess that's about $30 wasted.
