I love my Zebra F-402 ballpoint pen. I probably bought two of them like 5 or more years ago, and they’re refillable and reliable. I am about done with this tube of ink, and it’s just barely writing with a little dryer effort, but I know it will write until it is OUT! I have a million refills (literally maybe 20… they’ll probably dry out before I even get to all of them whoops) and Zebra makes all kinds of refillable stuff, and it’s great to reduce waste and always have a pen that I know works well. I do feel like I used to have two and don’t any more, which I suppose is why two is one and one is none!
