I used to use only lamy calligraphy nib on lamy pens now with the knox nib i can fit it on many of my jinhao pens and they looks way better than the lamy and is less expensive too

Now the knox nib itself i bought the 1

9mm calligraphy nib after put on my jinhao and nemosine pens they write just as good as the lamy

Now i learned to put less pressure on the paper when i write and hope that will make the nibs last longer i will recommend this knox nib for anyone who is tired of lamy pens and wants to have a more expensive looking calligraphy pens than lamy
