When you need to bring 6 ounces of your own "private stock", use this Stainless Steel Flask with Flip Cap. The Flip Cap is conveniently attached by a hinge, so no more worrying about losing the cap. Filling the small opening of a Flask from the large opening of a liquor bottle can be very tedious, so this 6oz Flask also includes a funnel. The funnel allows you to fill the Flask anywhere you want without spilling a drop. Great for any event you feel you could use an extra kick, and the smooth design makes it fit perfectly in your pocket.
