It&&';;s the stainless steel flask that never lets you down-unless of course, it&&';;s empty. The retro look, portable size, and slim silhouette on your insulated flask means that it can slip seamlessly into any situation. There&&';;s a wide mouth opening for easy refills (no funnel needed). And the stainless steel construction with leak proof cap makes it extra durable. Maximum of 20 units allowed per order. Feel free to combine colors!
