This is a Stanley vacuum growler. It's an item that keeps beer cold and delicious, making it easy to carry around. It has a large 1.9L capacity, but the sturdy handle makes it easy to carry with one hand. The wide mouth makes it easy to pour and clean. The lockable lid maintains a vacuum seal, preserving freshness. With its high cooling performance, it can be used not only for beer but also as a daily jug. It also works as an ice stocker when outdoors. (Quoted from the official website) *I have only used it for putting ice in it. There are black scratches on the surface as shown in the third photo. It works without any problems.
