what can he bring with to boot camp?

my boyfriend is leaving for boot camp soon and i was wondering what he can take with him? i had this idea to make him a small scrapbook that’s like the size of a standard book so it’s not a typical big scrapbook it’s much smaller. i wanted to give it to him as sort of a going away gift and something he can look at when he misses me. is he even allowed to take this with him?? he is going into the marines
