Retro51 Tornado PROOF - 紫色斜紋大號原子筆

It’s kind of wild to hold something that was never meant to leave the factory—the angled pinstripes catch the light in a way that feels almost hand-finished, and the weight is perfectly balanced in my hand. Knowing only a handful of these proofs exist makes every click feel a little special.

The angled pinstripes catch the light in a way that photos just don't capture, and the twist mechanism feels solid and satisfying. It's a pre-production proof, so knowing only a handful exist makes it feel extra special to actually write with.

The purple pinstripes look even better in person, and knowing it’s a pre-production proof makes it feel like a real piece of pen history. It writes smoothly, though I wish it came with a spare refill for the price. A fun addition to my desk.
