How about a personalized journal or notebook that he can use to jot down his thoughts and ideas for his poetry? Alternatively, you could also get him a collection of poetry books from some of his favorite poets or authors. If he enjoys attending poetry readings, you could also consider getting him tickets to attend an upcoming poetry event or workshop. Lastly, if he doesn't already have one, you could consider purchasing a nice fountain pen or calligraphy set to inspire his creativity.
Or you can get him a star map with the date when he was born.
