Just give cardboard purses to persons from highly cultural cities through cultural events, your enemy is the so called 'tote bag'. cardboard purses should be disposable, solid enough to transport something (e.g. some book the person bought) from a museum to the person house, but fragile enough to last only one week or so, IMPORTANT : the purse should be "cool" enough so people will prefer this to let's say the usual paper bag you get at the grocery store. Then, when you have taken the place of the tote bag, you can build the start-up that will manufacture and sell real purses, which will prove useful due to the downsizing of the men pockets, to transport phones, books, and coin purses.
