No doubts this pen has very smooth and fine to use and I never faced any problem of leakage of inks from this pen , I started using it because according to its price it provides really good quality to my papers and easily available on ever single stationary, its basic and simple design is very attractive for others and me as well I carry this pen mostly in my jeans or pant and its ink never ever spread or leak there . I can blindly trust them for sure and it last very long I don't even remember when I finished my last cello maxriter.
