These water bottles are the most effective way to ensure your favorite drinks stay at the temperature you want them to! Each 18 oz. bottle is made of stainless steel and features double wall vacuum insulation, a plastic lid with stainless steel wrapping and a wood-like design full wrap finish that can be customized with a one color imprint of your choosing. The lid and bottom part are brush polished. This is a great giveaway for brand exposure that can be used at home, on a hike or in the office!
