Many Stanley water tumblers that have been introduced over time have featured either solid colors or patterns on their exteriors. The Stanley Twilight Gradient Quencher 40oz Tumbler Blue has a gradient quality to it that provides it with a unique appearance from the start. Like most other Stanley tumblers, this one has a stainless-steel construction that makes it durable and ideal for everyday use. It also offers double-wall vacuum insulation designed to keep drinks hot or cold for extended periods. Additionally, its FlowState screw-on 3-position lid makes it easy to drink out of in several ways. But according to our experts, it's the special Twilight Gradient color utilized on the outside of this Stanley tumbler that truly sets it apart. It makes it more aesthetically appealing than an ordinary blue tumbler would be. The Stanley Twilight Gradient Quencher 40oz Tumbler Blue was released on October 25, 2023, when it initially retailed for $45.
