This would be such a cute gift! The one you found would work fine, but I also think it would be really nice to make one from one you find. I know that I absolutely love gifts that people have made for me because they put so much thought and effort into it! Not sure how big the globe listed is, but if you found a slightly bigger one, you may be able to fit more into it for the secret stash. I'm sure he will love it either way!!
