Carry your favorite alcoholic beverage in style with The Principals Liquid Body Flask. Made using a process known as hydroforming, this unique flask actually features a stainless steel construction. The Liquid Body Flask features two sheets of surgical-grade stainless steel, which are welded to each other. Water pressure then inflates the flask, resulting in a slightly different shape each time. In addition, the Liquid Body Flask comes with a capacity of five fluid ounces. It also comes in three colors including Stainless Steel, White Gloss, and Matte Black, depending on your preference. Small enough to fit in your pocket, the Liquid Body Flask makes it easy to carry your booze with you. Simply unscrew the top for a quick refill on the go.
