How do I restore the shape of the Mymia shell that has deformed?

In the event that the body of the Mymia bag is deformed, for example if it is crushed, the original shape can be restored by heating it with a normal hair dryer. Fill the body with paper, cotton or fabric so as to give the bag its original shape and point the phone at a distance of about 10 cm from the deformed point by moving it in a circular fashion. Once the shape has been restored, wait for it to cool completely before removing the previously inserted padding.
