If it is a real space pen, they are great! Husband and I used to have them. They had small ones that fit in one’s pocket, silver in color and with a pocket clip that is removable. I had it for years and years before I lost it. I would have bought a new one, but in the interim husband started hand turning pens and he made me one and I did not want to insult them. They really worked at all different angles, never tried under water.
