@juliedduncan Julie, I can tell you they are worth the money. I use one with waterproof ink and one with normal writing ink. Hence the 'need' for two. As in everything, there is a risk one can not get used to the tool. But I think they are quite versatile and I haven't heard of anyone saying they don't like them. Maybe liking some other type of nib better, but these are quite worth the money. I recommend you buy a converter, so that you can fill it with whatever ink you like. I have an F (fine) and an EF (extra-fine) nib, but I don't see any significant difference in the lines.
