Uni Ballpoint Pen Refill for Ballpoint Pen Uni-Ball Signo RT1, Red, 0.28 pt. - UMR82.15

hi this is a review video of the universe signal 0.28 this ballpoint pen or a gel pen is one of my favorites because it has very very thin lines but I wanted to do this video because I couldn't find a video where people compared it with the faulty pen like the sacral micron this one is a 0.05 with the language of data points and 20 millimeter and if we draw it and pressing hard it's basically the same so it's quite comparable with this one this 0.05 and here I have another one that's 0.1 with the language of 0.25 millimeter and if we draw here it's slightly thicker than a signal another pinyon that I think is quite comparable is the felt tip pen as well unit pain fine line there 0.05 so this one I'll draw it here on the left this one if we don't press too hard it's very thing and if we do press hard it's still thinner than the signal even when the signal is the fineness of the line list
