Totebags and Knotbags

Do you know the Knotbag? Is that some kind of totebag that comes to us from Japan? 
It is a traditional Japanese bag. It has two asymmetrical handles, one passing through the other to close it, and worn on the wrists. Tradition has it not to overload it so that it keeps its light and airy side. In the shape of a purse when worn, it can easily replace the totebag. Ideal as well with a small evening dress or for the summer ... it can also be used as a Bento bag or a snack bag depending on the model.
