The cork Olivia Bag will be a great addition to your bag brigade.

This bag is made entirely from cork on the exterior. Yes, cork , like wine corks! It is harvested from the cork oak tree (without harm to the tree). It is lightweight, durable, and a sustainable textile.
 
The outside pocket is perfect for easy access to your phone.  The interior is always coordinating. The cork strap is adjustable and detachable.
