POW Comic Flask- 6, 8 Ounce - Custom, Personalized- Many Colors (6 Ounce, Orange - Matte) 25 Color Options & 2 Sizes! 6 Ounce Flask: (3.75 x 4.5 x 1 inch) - 8 Ounce Flask: (4 x 6 x 1.25 inch) Our flasks are freezer-safe and waterproof! Beware of other brands that use flimsy paper and/or chemical sealants: they will bubble and peel away after being stored in the freezer or soaked in the sink! Each flask is handcrafted. Once we design and cut the pattern into the vinyl, we carefully peel the design out of the vinyl piece by piece. We then align the vinyl so that it is centered on the flask. What you get is a unique and useful flask to call your own. All of the designs wrap completely around the flask and overlap in the back. The layout/positioning of the vinyl will vary slightly as each flask is a handmade, unique piece. All flasks are gift ready! Each flask will arrive in a cotton muslin drawstring bag. The cotton used is 100% All Natural Cotton domestically grown (and sewn) here in the USA!
