You know, you could go for something different, and get yourself an old Gillette Travel DE Razor. They always come up on eBay in nice little cases, and are not very expensive.
This might be a problem if he's planning to travel by air and only planning on taking carry-on luggage (DE blades are verboten​, but otherwise *very* sound advice.
Since the OP hasn't been on the site in over 7 years, sadly it's sound advice he'll likely not get.
If you desire to use disposable, Bic metal is about as close a real DE that you can get....that is if you don't actually find some disposable DE's, they really do exist, but both my votes go to Bic metal, loved them through college, outperfoms the 4-5 blade cartridges everytime for me
