uni-ball AIR micro vs Pentel Tradio TRJ - ¿Sustituirán a las estilográficas?

A comparison of two Japanese-made writing instruments distinguished by a slight variation in line width, making them a potential alternative to fountain pens. The first is the Uni-Ball AIR Micro. This writing instrument has a rollerball or liquid ink pen format but can write with varying line widths. Its BiC-style nib features a shock-absorbing system that allows for comfortable writing and noticeable line width variation depending on the pressure and angle of use, ranging from 0.3 mm to 0.5 mm. The second is the Pentel TRJ. A full-size fountain pen with a triangular felt nib made of synthetic fiber, allowing writing on both sides, each offering different flexibility (and line width). This allows for a line width of 0.4 mm on the stiffer side and 0.7 mm on the more flexible side. We tested them with the blue permanent ink cartridges that came with them.
