I love the Lamy Aion fountain pen. It is girthy and feels good in my hand. And it writes beautifully. One of the interesting thins about the pen is that it has a different nib than the rest of the Lamys. At first, it looks the same. But take a closer look and the nib is curved as opposed to the regular nibs for the Safari's and Studio's, etc. which have a nib that is flat on top with the sides folded down. There are little creases on the Safari nib, where there are none on the AION> It is part of the design of the pen. Much to my surprise, my pen came with not an AION nib, but a Safari nib. I'm not pleased that I have to purchase an AION nib to maintain the design of the pen. I know it is a somewhat small thing. But if you are going to offer a pen model in all nib sizes, one should not just put any old nib on the pen. The box was factory/distributor marked "Medium" which was crossed out and a "B" written next to it. So I must assume the store swapped the nib. But honestly, that's not a good practice. If one does not have the entire correct pen in stock, nib and all, then don't offer it. I was easily able to purchase a correct nib for the pen from another retailer. But that increased the cost of the pen $15. But delivery was fast. And I love the color of the pen.
