Ti Arto EDC：終極可換芯日常攜帶鋼筆

The machining on this pen is flawless — the titanium feels solid but not heavy, and the grip texture is just right for long writing sessions. I've swapped in three different refills so far and every one seated perfectly with zero tip-wiggle, exactly as promised.

I’ve tried a ton of pens that claim to take multiple refills, but this is the first one where I haven’t needed a single hack or extra piece—it just clicks in and writes perfectly. The solid titanium body feels incredibly sturdy in hand, and I love that I can switch between my favorite gel and ballpo

The grip on this thing is perfectly knurled, and swapping in my favorite gel refill took less than ten seconds with zero wobble when I write. It’s already replaced three pens on my desk, and the solid titanium weight feels reassuringly expensive in hand.
