That's a great gift idea! Here are a few options for you to consider:
1. Personalized Fountain Pen: If your boyfriend has a few favorite brands, you could consider getting him a fountain pen that is engraved with his initials or a special message. Personalizing the pen can add a lot of sentimentality to the gift, making it truly unique for your boyfriend.
2. Limited Edition Fountain Pen: Many companies release special edition or limited edition fountain pens that can be quite rare and valuable. If your boyfriend is a collector, he may enjoy adding a one-of-a-kind pen to his collection.
3. Fountain Pen Stand: If your boyfriend has a lot of pens, he may appreciate a stand to display them on. There are many varieties of pen stands available, from wooden models to acrylic and metal stands.
4. Fountain Pen Ink: If your boyfriend uses his fountain pens to write, he likely goes through ink quickly. High-quality inks in unique colors or brands can make great additions to a fountain pen collection.
5. Fountain Pen Leather Case: To protect and transport his fountain pens in style, a leather case can be a great option. There are many different styles and sizes available, so you should be able to find one that matches your boyfriend's aesthetic.
Or you can get him a star map with the date of your anniversary.
