It is a new concept for manufacturers of a kind of prepaid return mailing label whait is inside the cell phone itself. When the user does not want the phone or more, they can simply strip the label out, paste it on the phone, and just mail it off. Labels can be stuck inside the battery compartment or under the battery cover. Labels may include the address of a mobile recycling center. No need to look for information how to recycle it. Just peel it, stick it and just meail it.
