The nib shutter with spring, air tightness is ok! The protrusion on the pen core corresponds to the notch on the thread, and it is aligned and inserted for installation. The accessories include an ink applicator, two empty ink sacs, an ink sac stopper, and a dropper for filling the ink sac. The accessories are very attentive. Its not convenient to bring an ink bottle when you go out for a short distance, so put an ink sac with the ink and bring a spare, which is very safe. Pressing the pen is especially suitable for intermittent writing. It's the kind of occasion where you can stop and write. Many pen pals are not used to this pen holder. This time, the finalist also very intimately released a version without a clip. If you are not used to it, it just means that the pen holding posture is abnormal. Abnormal pen holding posture makes the pen easy to scratch and white, and it is not conducive to calligraphy. Everyone cares about the writing quality of the pen nib. The iridium grains I have on hand are pretty good. The iridium grains are round and full, with enough writing margin, and the center seam is just right. It has a proper writing surface polished to make it smooth and easy to write. In fact, such a tip is good enough to use. Putting on the golden tip, the improvement is also very limited. It can be said that changing to a gold tip has improved writing. Package Contents: 1pc of Fountain Pen
