How about a personalized seashell collection box where he can display and keep his favorite seashells? You can also add a customized message or his name on the box to make it more personal. Another idea would be to plan a romantic getaway to the beach and spend the day collecting seashells together. You can also gift him a special seashell necklace or bracelet that he can wear and be reminded of your love and his collection.
Or you can get him a star map with the date of your anniversary.
