It is incredibly smooth; it's designed specifically for document signing, so it glides really well on paper, and has a really nice, juicy inkflow!

The Bic Round Stic is definitely one of the greatest of all time haha; I think I've used those at every single job I've ever had LOL. She's consistent, affordable, and last 3000000 years a pen (❁´◑`❁)

If you like that style of pen, I think you'd like the Pentel R.S.V.P line; they're a little thinner but have a similar inkflow, and write as smooth as room-temp butter. The black colour was my daily pen for years because it dries down fast and I can write quickly.
