16021 Noodler's Ahab Clear Demo Brush

Watching the ink slosh around in the clear body while I write is oddly hypnotic, and the flex nib gives just enough line variation for my daily sketching. It took a few minutes to get the feed primed, but once it flowed, it handled my cheap notebook paper without bleeding through.

The clear barrel is the best part—watching the ink slosh around while I write makes it feel like a tiny science experiment in my hand. The feed and nib are easy to pull apart for cleaning too, which I appreciate since I switch inks constantly. This thing writes wet and smooth, exactly what I wanted.

The clear body is great for checking how much ink you have left without unscrewing anything, though the feed does take some fiddling to get flowing smoothly. Once it warms up, it writes with a nice, expressive line.
