ROO pocket
We call it "ROO POCKET" because it is capable to keep a lot more than it looks just like a kangaroo's pouch
There is a ROO POCKET(with a zipper) on the side in which you can put small articles such as a wallet and tissue papers which are likely to be buried underneath in a bag and from which you can take them out easily.

Portable
There is one inner pocket & one outer side pocket (the “ROO-pocket”).
You can even fold the bag into the inner pocket and make it a compact size of 12 x 13cm for easy portability.
