A unique and meaningful birthday gift idea for your boyfriend who enjoys balloon art could be to arrange a private balloon art lesson with a professional balloon artist. You can look for a local balloon artist and book a class for your boyfriend. You can also prepare a balloon art kit that he can use to create his own sculptures at home. You could include a book on balloon art techniques, a variety of balloons in different colors and sizes, and some basic tools like a balloon pump and scissors. Additionally, you could make a cute balloon-themed birthday card to go along with the gift.
Or you can get him a star map with the date when he was born.
