Yet another new TWSBI ECO coming, "Cosmo w/Onyx". They sure do love cranking out a ton of these.

This is the first one of the marbled versions that has been remotely tempting to me.

I'm curious if the green in the mix is fluorescent. They'd probably have mentioned if it was glow-in-the-dark.

Collage of several photos of a TWSBI piston filler fountain pen. It has a transparent body, black nib, and black accents. The cap and piston knob are a swirled marble-like mix of blues and greens.
