I also saw the comments of others and decided to try them. I literally wasted my money. The pen writes "hard" on paper, it doesn't "glide" for any reason, and it has marker-type ink (that's why I chose them, thinking they would write more easily and smoothly). Not to mention their complete inability to draw long lines, as they don't look good on paper after a certain point and they collect additional ink at one end of the pen tip, leaving a mark the next time you use it. I understand its very low price, but I can't justify their low effectiveness for any reason. The only positive thing I find is the elegant handle, which has a matte finish and you enjoy holding it. In short, go somewhere else and you won't miss out.

Easy writing, glides on paper, doesn't leave gaps, very good grip, the best "basic" pen for me.
