"I buy t-shirts online and they always come wrinkled and I always run out of coat-hangers. So I designed a sustainable, reusable way to send and keep your t-shirts."
The Hangerpak could conceivably be made out of any post consumer recycled material like cardboard or recycled plastic, and when you are done with the hanger it can be recycled again.
The "Greeness" of hanging your t-shirts on a hanger is definitely a little questionable, but I'll be honest, I'm guilty. Obviously using no hanger and minimal packaging would be the greenest route, but I love this innovative way making things we make serve several functions. This reminds me of the Flat Panel TV box that turns into a TV stand.
