This new concept from Industrial design company Priestman Goode is essentially a cardboard disposable phone, called the Post A Phone. What you get is a 4mm (0.16 inch) thick cardboard landline handset that pops out from a backing board. That’s it. It’s ready to plug and make calls.

The whole thing can fit in an envelope. Say a cell phone customer loses their phone. This can be mailed right out to them. Environmentally speaking, it’s cardboard so it won’t hurt the environment.

All signs point to it’s main use being a marketing tool, however. Remember those AOL CD’s that were breaking your mailman’s back? Soon there may be phones coming to your mailbox, branded with company logos. It remains just a concept for the moment, but I’m sure we will hear more from this thin phone.
