This isn't your basic pocket flask, this unique flask has a look all it's own. Keep an eye on how much you've drank out of your flask by looking through the unique window panel found in the middle of this stainless steel flask. You'll always know how much is left, and when to refill. Each flask comes engraved with your choice of the groomsmen's name, monogram, or initials on the top front of the flask for an added touch of personalization. Your groomsmen will love the unique style of this timeless gift.
