Manga G Tachikawa Classic Fountain Pen

This pen’s construction is ok but comes with many flaws. The ink was leaking from every corner no matter how tight I pushed the ink cartridge and scred the back. It was also flodding the nib way too much almost making it unusable. It’s unfortunate that I got one that was useless. I discarded it after many attempts to make it function and getting ink all over my hands.
