Groomsmen

We found a set of alcohol glasses and ordered one box each. And then we found fun dress socks at Express and them all one at the rehersal the day before when we gave everyone gifts, We have some cute pics on the wedding day with all the boys in their socks!

Shop like it's Christmas or their birthday. What are their interests/hobbies?

You could also do something that's the same for all of them, but you KNOW they'll like/use. Our rehearsal dinner is going to be at a steakhouse in a casino (hopefully - can't officially book until they open back up) and we'll all go gambling afterwards, so part of the wedding party gifts will be a casino voucher. It's the same for all of them, which is generally discouraged in these forums, but it's also something I know they'll use because we're all right there and that's the entertainment for the night.

I'm not sure if you are just helping your FH brainstorm, but I definitely think the groom should be the one picking out gifts for the groomsmen. My FH got dopp kit bags that are monogrammed along with customized and engraved flasks for each groomsmen. I would not have chosen the exact items and customizations that he did, but they are his friends and his gift to him should represent their friendship. I can only imagine what my bridesmaids gifts would have looked like if he picked them out!

My husband gave his a Swiss army knife with their names on it and cuff links with their initials on it
