Review: So glad I bought these- a great surprise - I have 9 pens now- all different sizes and prices from $10 to $75. These nibs (in my Black Forest pens) are the smoothest and best writing -and have become my go to for any kind of drawing. I bought the EF F and Bent nibs- the ink flow is great in all of them. Beautiful , effortless lines. These are by far my fave pens and nibs and the ones I reach for first .The EF nib is especially remarkable. It lays down lines almost as fine as a hair. I’ve been drawing with it all day yesterday- for hours and hours- and never once did it skip or scratch. This morning I uncapped the pen and it instantly gave me a beautiful line. Super impressed and highly recommended. Review: Recommended - These were just what I was looking for . The extra fine nib is much finer than the extra fine brass nib my Hongdian M2 came with , making it better for writing in my pocket notebook and getting fine details . They still have good flow and not scratchy . I also think the color makes my pen stand out more . Recommend ## Features - Easy to replace the nib by twisting it out and back. Please remove the cartridge or converter before twising the nib out. - These nibs are not standard size, they are only compatible with Hongdian forest fountain pen 1850, 1851, 1861, M2, M1, 1843, 6013, 517D, 517S, 525, 1843 and 920 Series - Package: 3 nibs with black section ( 1 x EF nib 0.38mm, 1 x F nib 0.5mm, 1 x Bent Nib 0.7-1.2mm) - PS: Please remove the converter before twist the nib section out.
