Thanks to Darhang for this fancy and unique designs.

I am very satisfied with this practical tumbler, when I am going for hiking or swimming. Not only for sports, but walking with dogs and going for shopping as well.

Even my colleague asked me to have one for using in the office once she get interest in the Korean styled design.

In Switzerland there are many kind of bottles and tumblers but not designed well because most of that is only considered as it for sport activities.
