Retro51 Tornado PROOF - 지킬 박사 & 하이드 씨 블루 볼펜

Getting my hands on one of these pre-production proofs feels like owning a tiny piece of pen history. The blue lacquer has a depth you just don't see on production models, and knowing only a handful exist makes every stroke feel special.

There's something almost magical about holding a pen that technically shouldn't exist yet. The blue resin catches the light differently with every turn, and knowing it's a pre-production sample makes every signature feel a little more special.

Got lucky and snagged one of these pre-production proofs, the weight and twist mechanism feel perfect in hand. The Dr. Jekyll & Mr. Hyde blue finish is even more striking up close than in the photos.
