Groomsmen Gifts They Won’t Throw Away

I’m looking for suggestions for good gifts to give about 15 people at my bachelor party. I like upgrading basics that get used every day with nicer versions that improve quality of life. Knives are out, because most people will travel by plane. I like the idea of something that could be personalized or engraved, but it’s not a must. $50 or so feels like the sweet spot. Thanks!
