This is a Delta Dolce Vita Slim fountain pen. The nib size is B (broad), but Delta's B nib is a very usable, moderate thickness. (I feel it's similar to a Pilot M (medium) nib in terms of thickness). The writing feel is smooth and has a fantastic sensation. I purchased this as a deadstock, unused item in 2023. I have used it about 10 times. All accessories, such as the box, are included. It is in beautiful condition with no noticeable scratches, but please understand that there is some minor wear and tear from use.
