Stainless Steel Flasks slip easily into a pocket or purse. We've improved this popular product by replacing the plastic hinged top with a simple stainless steel screw-on, removable cap. Made from high quality, food-grade stainless steel, sublimatable flasks do not contain BPA or any other toxins. Dye sub flasks open quickly, close securely, and are even easier to personalize than before. Email us your photo, business logo or design. We can add whatever text you would like!
