Although the choice of pen is subjective, I believe this is one of the best pens you can buy. The POSITIVES/NEGATIVES are listed below for you to see.
POSITIVES:
+Beautiful and sturdy construction. This pen has a cloud design corresponding to the color you purchased, and it is very beautiful. It is also durable BUT, BE CAREFUL WITH THE TIP AS IT BREAKS OR BENDS EASILY! Make sure to close the cap when not in use because the tip is the most vulnerable point of this pen.
+Long-lasting. This pen will surprise you with how much ink it has and how long it can serve you. Even when it seems like there is no ink left, it continues to write for a few more days.
+Does not "smudge." Because its ink is not in liquid form, it is difficult for excess ink to come out and stain the paper. It is difficult but not impossible, as with any pen, it sometimes happens.
+Clip to attach it to your shirt pocket and to prevent it from rolling off the table.
+0.5 mm tip. This fine tip allows you to fit more text in the same space compared to a pen with a larger tip. The tip is not so fine that it "scratches" the paper, but not too large that you waste lines; it is in between these two extremes. However, it should be noted that THE TIP IS THE MOST FRAGILE POINT OF THE PEN AND YOU MUST BE CAREFUL NOT TO BREAK OR BEND IT.
+Neutral design. This pen can be easily used by both right-handed and left-handed people.
NEGATIVES:
-Non-refillable ink cartridge. Unfortunately, the ink cartridge in this pen is not refillable, so once the pen runs out, it goes in the trash, which is bad for the environment.
-Weak tip. As I mentioned earlier, the tip is very weak and cannot withstand drops, so make sure to close the cap when you are not using the pen.
-Colors. With the 0.5 mm tip, there are only 3 colors: blue, black, and red. For some reason, green is not available; it is only available with the slightly thicker 0.7 mm tip.
Overall, this is a very good pen for everyday use, but it could be better, especially the non-refillable ink cartridge is something that tarnishes the good image of the pen. If you want to buy it, I would suggest getting more than 1 because the 3 euros for shipping are not worth it for 1 pen that only costs 1.60 euros. I hope my review helped you with your purchase :)
