T-shirts bought on-line, always come wrinkled and, obviously, without coat-hangers. So it was developed the concept of a sustainable, reusable way to send and keep t-shirts: the package can be opened to create a coat-hanger. The packaging could be made from recycled material, whether it is card or plastic and the only waste is the green tear-away tab. The t-shirt in the photo is from Threadless.
