筆芯 - Schmidt P950 | 0.7mm | 加壓原子筆 | 黑色

Wrote through a soggy notepad at the airport the other day and the stainless steel tip never skipped a beat. This pressurized 0.7mm lays down a clean, solid line even when I'm holding it upside down.

Finally found a refill that keeps up with my fast note-taking even when I press hard. The pressurized mechanism means no skipped letters or faded lines mid-sentence, and the black ink stays consistent right up to the last drop.

The stainless steel tip feels solid and the pressurized cartridge keeps the ink flowing perfectly even at odd angles, which is a lifesaver for quick notes. I've used it for about two weeks now and the black line is still crisp and consistent every single time.
