Meet the AromaCase: an iPhone case that holds 20 ml of your favorite perfume. It has a replaceable cartridge and works with any brand of perfume. Just press the button on the upper part of the case to use it. The case does not look too bulky for what it offers. The cartridges are made of heavy-duty rubberized plastic and don’t break easily. You can order new cartridges online. We are not sure this is the greatest idea, but you can always find out more about it on Kickstarter.
