How about gifting him a personalized bullet journal? You could get a plain notebook and decorate the cover with his name, his favorite colors, or bullet journal images that he loves. You could also add some stationery items like colorful pens, stickers, stamps, or washi tape that he can use in his bullet journal. Another idea is to gift him a set of bullet journal stencils to make his designing easier and cleaner. Finally, you could get him a book on bullet journaling or sign him up for an online workshop to help him take his bullet journaling to the next level.
Or you can get him a star map with the date when he was born.
