The Saucy Flask keeps more than just condiments. Disguised as mango mint, kooky ketchup, and tangy tangerine BBQ, these collapsible flasks can be filled with any liquid (including booze!). They contain up to 16 ounces and come with a compression seal safety lid. In addition, the company donates 50 percent of the profits to five different social causes. The Saucy Flask is available for purchase online.
