They're good for the price, except they have a rather wide range of widths in single nib size. According to Lamy it's +/- 0.06mm which makes 0.12mm difference at extremes, Also, you can't get black stub nibs.

But keeping the above in mind, I think this is the easiest (and probably the cheapest) way to get a wide range of nib sizes. Also, I can't stress enough the fact that you can hot swap the nibs (i.e. with an inked pen) is incredibly convenient and not talked about enough.

The Z50 steel nibs in stub 1.5 used to be my favourite, next to the 1.1 stub. I also have some of the 1.9 stubs on pens inked with shimmer inks for fancier writing. My handwriting is large enough that using these nibs for everyday writing works well, and I enjoy the depth brought by the wide strokes.

The ease with which one can switch these nibs (Z50 in silver or black, Z52 from the LX line, Z53 from the Aion line, Z55 14kt gold bicolor) and the range of widths available is great.

The only reason the 1.5 stubs are no longer my favourite is that on paper of lower quality (for everyday scrap work), the interplay between the paper and my wrist/hand results in sections of the paper where the stub nibs will skip.

Im Recived my order Im very happy Seller is good and quick to reply email

For owner of Lamy pen this is a must have for you can't believe that just charging the nib my pen is able to do more task from writng, sketching and with broad nib I will be able to use my pen with the visualizer. Took 1 week to arrived at Chiang Mai. Package is well enough to prevent those nibs from killing each other. Great service :)

Those Lamy nibs write very well, not scratchy at all, plus they're very easy to change and affordable. A lot of possibilities and the same nibs for most Lamy fountain pens, what's not to love?
