Birthdays are good times for guys to get all kinds of gadgets. I'm sure they will love anything you decide on.
But I encourage you to also write some things down for them. Maybe in a card they can keep. Maybe on the background or matte of a photo in a frame. Or some kind of keepsake shadowbox of little things from over the years. They like goodies. But they also need something they can look at that will remind them how much they are loved, and how special they are ... each one of them.
