How about getting your husband a high-quality leather pen case to store his fountain pens? Or you can get him a limited edition fountain pen from his favorite brand or a one-of-a-kind vintage fountain pen. Another idea could be to get a personalized fountain pen that has his name or initials engraved on it. Alternatively, you could book a calligraphy or penmanship class for him to help him improve his skills with the fountain pens he already has.
Or you can get him a star map with the date of your anniversary.
