Pelikan's classic Souverän model. The nib is F, 18k gold. I bought this about 10 years ago and loved it, but I haven't used it at all recently, so I'm putting it up for sale. I checked the current model, and the M600 seems to be 14k gold, but this one is 18k gold. There are no problems with writing, and it has been cleaned. Regarding the condition: There are some purple ink stains on the part of the barrel where the cap fits and on the part where the cap is attached to the barrel when writing. I tried cleaning it, but it didn't come off, so I've listed it as having scratches and stains. Please consider this item if you understand that it is a used item. The pen case is a genuine Pelikan one. There is no original box, so it will be simply packaged and shipped. - Color: Black and green stripes - Material: Metal and leather - Design: Gold trim - Features: With clip, cap type Thank you for looking.
