Not going to lie, I do the same. I love playing with cheap pens and just got a bunch of Jinhao 51s and a few Wing Sung VACs. It's hit and miss but you do find some gems (some of their resin colors look amazing). Plus, if you accidentally drop one in the toilet at work you don't get sad.
Downside is having so many pens on hand leads to inking too many pens at once.
I probably should experiment with these "micro blog" options and write up a few reviews. There are a ton of garbage AI generated "reviews" for these cheap pens, and it getting hard to find pens that come from a actual factory / distributor that has a ton of capacity.... vs someone trying to scam.
