Hi, everyone! We just wrote a review of the Aurora Minerali series demonstrators - tried to provide some advice as to why we like them so much (all their nibs are made in-house!). These are definitely some of our favorite demonstrators out there! Let us know what you think or if there's another demonstrator you like more! https://www.truphaeinc.com/blogs/truphae-news-and-stories/aurora-88-limited-edition-minerali-fountain-pens
