How about getting her a Blackpink merchandise like official light stick, t-shirt, hoodie or phone case? You can also surprise her with a set of concert tickets if they have any upcoming shows near your area or a framed poster of one of their concerts. Another idea is to create a scrapbook of all your memories together with your girlfriend which includes pictures and some lyrics from Blackpink songs as well. Alternatively, you can also get her a personalized gift with Blackpink theme such as a coffee mug or a custom-made necklace with her favorite member of the group's name on it.
Or you can get her a star map with the date of your anniversary.
