The exterior of your DODOcase will wear like a hard back book. It is natural that you'll start to see signs of wear as you continue to use the DODOcase. As DODOcase customers use their cases in different ways, this wear will arrive at different times. Our book binder tells use that although wear is occurring, the integrity of the cover should not be compromised. Depending on the type of user you are, some sloppiness could be expected to arrive.
