This pen has a fantastic quality nib ("F"), that writes super smooth in all directions pleasant rounded construction/design, and a screw-on type cap. Comes with a large capacity converter for bottle ink, or works with 2.6mm catridges. Dream come true, and does not cost a lot of money. The one in orange transparent plastic is particularly beautiful-looking in real life.
Forgot to mention, unlike many other Jinhao pens, this one works great with the cap posted on the back of it as you write. They got the balance just right, in case you want to use your pen this way with the cap on the back.
Very good.
