When I saw these customized bow tie flasks from The Hair of the Dog I thought they'd make a fantastically fun gift for the groomsmen! All flasks are stainless steel and can be personalized with names, dates, initials, etc. You can even select a different background color to coordinate with your wedding colors.
And, if you don't want to leave the bridesmaids out, not to worry, there are custom flasks for the bridal party, too. Even the bride and groom, if that's how they want to roll!
There are a slew of styles and colors so finding the perfect fit to commemorate the day shouldn't be too difficult. Keeping the groomsmen from needing a little "hair of the dog" the day of the wedding? That may require a little more effort.
