This listing is for the Delta Dolce Vita plasti display case/box shown in the photos. (N.B. No fountain pen is included in this sale. eBay's computer apparently found that hard to believe, as it asked for nib size, material, etc.) This case will work with several other models. I used it for my Delta Alfa Romeo Giulietta, which is for sale in a separate listing. You simply unscrew the threaded caps holding the front plate in place, insert your pen, thread them back in, and you are set.
