Cigarettes, alcohol, beer, boys' favorite drinks, instant noodles, bread and other convenient foods (boys play computer games in college and have no time to eat). There are socks and underwear (boys don't like washing clothes very much, not to mention these little things that are easy to get dirty, and they throw away a lot after wearing them once). There are also toiletries, razors, selling words, plush toys, small gifts and so on. Boys don't need it, but girlfriends can use it!
That's all I can think of for the time being I wonder if I can help you!
