19210 Polar Green

The bottle’s a solid 3 oz, and the ink flows beautifully even when my apartment drops to near-freezing at night — no clogging on my dip pen. That lubricated feel is real, too, it glides way smoother than my usual inks.

The ink stayed perfectly fluid during a ski trip when my other pens were freezing up, and the green shade has a nice deep character that shows up well on cheap paper. The 3 oz bottle is generous for the price, and the lubricated feel made my fountain pen glide smoothly even in the cold.

Took it out on a below-freezing morning and it still flowed smooth as butter from the first stroke, no clogging or skipping. The 3 oz bottle is a solid size for the price, and this green has a nice deep, wet look on paper that makes me want to write more in the cold.
