LAMY Z 50 Joy calligraphy nib for fountain pens. Calligraphy nibs do not have a rounded iridium tip, but a straight, flat one. This allows you to create writing with varying line thicknesses. It is made of high quality, durable and long lasting stainless steel. Suitable for all LAMY fountain pens (Safari, Vista, AL-star and Joy) except Lamy 2000. By replacing nibs as needed, you will ensure the longevity of your LAMY fountain pen and the consistency of your writing. Tip: When choosing the right nib width, consider the size of your handwriting: the smaller the writing, the finer the nib (M), (F), or (EF) should be. On the other hand, a broad (B) or (BB) nib works better for larger handwriting.
