My listings are only on Mercari. Thank you for viewing. As a limited-time bonus until January 11th (Sunday), I will also include the Octanium nib (F, fine) shown in images 2 and 3. This allows you to use it as a fountain pen as well. It is said to be more durable and have a better writing feel than a 14K nib, and it is also highly rare, so please consider it. I am selling a rare gold Grenade model rollerball from Parker's 90s masterpiece, the Premier series, to organize my collection. I will also include a refill and the section of a 75 series fountain pen. This is a wonderful piece with the Premier series' characteristic finely angled cap ring and top design. When it was released, it was a high-end model second only to the Duofold, with a list price of 50,000 yen. The ring on the fitting part is also gold, making it very glamorous. As shown in the images, it is a beautiful item with no noticeable scratches or stains, and the yellow gold color remains vibrant. As some of you may know, the Premier series came after the 75 series, and there are some areas where the specifications are mixed. The Premier section is compatible with the 75 series fountain pen section, and you can use it as a fountain pen by replacing it. Some 75 sections become loose, but this one closes with a satisfying click, so please rest assured. This is a rollerball, which is even rarer among the rare Premier series. It is a model with a strong presence that will elegantly enhance the owner's hand, so please consider it at this opportunity. I will carefully pack and ship it via Rakuraku Mercari or Yu-Yu Mercari. If you are not satisfied with the product after arrival, I will accept returns including shipping costs. Thank you.
