You could get him something that shows you put thought into it. Try to think of something that he has mentioned wanting or needing lately. Alternatively, you could get him something that you know he loves or something related to his hobbies. If you are looking for something more personal, consider getting him something that has sentimental value or something that reminds you of him. The possibilities are endless! Whatever you choose to buy, make sure to get it wrapped and decorated nicely. Good luck!
