Premium Resin Special Release

The shop has been hard at work to turn hundreds of European acrylic acetate and cellulose acetate rod stock into some incredible looking fountain pens. The first of these is ready for purchase featuring an amazing aqua shimmer swirl in pitch black acrylic. This material was sourced from Vince at Turner's Workshop in the UK, showed up years ago and we've finally gotten around to working with it. It machines easily and polishes to a brilliant shine with the silvery aqua-blue blazing forth from the black, we knew it would be another oceanography themed pen right away, and landed on the Black Sea for inspiration. 

The Black Sea Vertex Special Release is a small batch release featuring premium European (Erinoid) acrylic acetate. The bodies and caps are fully-machined in-house, and each piece is then taken through a multi-step wet-sanding and polishing process with a final soft-wheel technique that brings out the shine. Select from a variety of Makrolon, aluminum, or brass grip sections to customize your pen and a variety of polished steel nibs. Each pen ships with a Schmidt K5 converter and two black Monteverde ink cartridges in our recyclable packaging.

Hannah ★★★★★

The acetate body has this warm, almost honey-like translucency when light hits it—way more dimensional than a plain resin pen. Threads are smooth and the cap posts securely, which is what I care about most. It's easily the best-looking pen in my daily rotation now.

Ava U. ★★★★★

The depth of color on this pen is unreal—the European acetate rod stock has this swirling, layered look that shifts in the light. It's my favorite desk piece now, and the resin feels dense and well-balanced in hand.

Alexander I. ★★★★★

The acetate material feels surprisingly substantial in hand, and the way the swirls catch the light shifts from deep black to a faint blue-green. I've been rotating it into my daily carry all week, and the cap threads are smooth every single time.
