In this video I take a deep dive into the new PenBBS 470, and yeah—this one grabbed my attention because it’s not just another pretty acrylic pen. The Galaxy Blue material looks fantastic, but the real story is the filling system. It’s “vacuum-based,” but it’s not a standard vac filler and it’s not a piston either. Instead, you’ve got a simple pull-knob setup that uses vacuum pressure to pull ink straight into the body, and I walk through what that actually feels like in use and why it’s different from the usual mechanisms people expect. I also break down the design details—classic Chinese-inspired touches on the finials and cap band—and then get into the practical stuff I always care about: how it writes, how it cleans, and how easy it is to keep running long-term. Mine came with a smooth medium steel nib, but I talk about the bigger win here: PenBBS nib unit versatility, including specialty grinds and even gold options. I finish up with serviceability and durability, because if a pen is a pain to maintain (or can’t be maintained), I’m going to call that out.
