Groom Gifts!?

There's a tradition where the bride and groom exchange gifts or notes prior to the ceremony. What did you give or what are you planning to give your grooms? We are pastors so we don't drink. I like the socks "in case you get cold feet." But that seems like it should be part of a package. We did full bridal party proposals. Im a designer so my girls got custom made flip flops, bling tshirts, personalized tumblers, personalized totes and garment bags, custom blinged out hangers, a sash, and a 911 kit filled with all the little things they need for the big day. After all that, I can't skimp on him. We are both preachers. Notes aren't hard. But we always talk and we have personal vows. If I get him one more watch he'll probably call it all off lol. Aaaaargh. Total blank. Budget about 200.00. I don't care if he gets me anything. Im having my dream wedding. He deserves something special. He's awkward. He loves tools and books lol. That's not gonna cut it 🤦🏽‍♀️. He's also a nerd and loves all things Marvel and Star Wars. I prefer something more elegant but maybe Im over thinking it. Help!
