In this video I’m putting the Diplomat Aero Oxyd Brass Stripes under a very left-handed microscope—because if a pen is going to smear, skip, or feel weird on the page, I’m going to find it fast. I walk through the fit and finish, the whole “oxyd brass” vibe, and what that striped Aero body actually feels like in-hand during real writing (not just a two-second scribble). The big focus is the 14k nib: how it behaves, how controllable it feels, and whether it’s the kind of gold nib that actually earns its price when you’re writing as a lefty. I also talk about what I inked it with and why ink choice matters a lot more for left-handed writing than people want to admit. If you’re curious about pairing the Aero with a fun ink like Tono & Lims Sachertorte, or you’re hunting for paper that won’t turn a wet nib into a smear-fest, I call out options like Artik paper and how I approach testing. The takeaway: this is a pen that’s all about the experience—materials, balance, and nib feel—and I’m breaking down whether that experience works in the real world for the way I actually write.
