Product description: Double wall, 12 oz stainless steel Traveler tumbler with 360 Lid. 

What we like about this mug: Miir has become the leader in manufacturing technically superior drinkware products in a way that is both ecologically conscious and committed to finding ways to give back. 

With Miir's practices as a foundation, we love having the opportunity to offer a custom designed mug that keeps your hot drinks hot, your cold drinks cold, is BPA free and has all the drinkability comfort with the 360 Lid.
