A great idea for your girlfriend's birthday gift could be a custom pin or button made just for her. You can design one based on a favorite hobby or interest of hers, like a musical instrument, a plant, or her favorite book/movie character. You can also create a pin or button of a special moment you've shared together, like a favorite quote or a cute drawing of the two of you. Another idea could be to curate a set of unique and vintage buttons from different eras or places for her collection. This would show that you've put thought into selecting a gift that matches her interests and passions.
Or you can get her a star map with the date when she was born.
