An easy way to spoil your groomsmen—and show your appreciation—is with a groomsmen gift box set. Etsy has a lot of gift box options for groomsmen, including cocktail sets, grooming sets, cigar kits, cufflink sets, and more. You can even create your own gift box by filling an elegant wood keepsake box with a few of your groomsmen's favorites, like snacks, a flask, slick sunglasses, or other meaningful mementos they'll cherish.
