The box will contain a DVD cleaning cloth provided by LoveFilm, a roaring fireplace DVD by Diageo, an O2 SIM card pack, bath products by Original Source, a Cadbury granola bar and book samples from Harper Collins and BBC Audio Books.
The Matter box concept, created by Matter Media, was tested earlier this year when Royal Mail sent out 1,000 boxes to UK males. The buzz this generated provoked mentions on more than 100 blogs and websites and prompted more than 65,000 people to register to receive the box.
Antony Miller, head of media business development at Royal Mail, said: "Advertisers are no longer able to rely only on consumers seeing or hearing their messages to boost sales -- they now have to really engage people to stand out."
Tim Milne, from Matter Media, said: "Interest in Matter has been phenomenal from consumers and brands since the first box was delivered.
"The beauty of packaging and delivering an endless variety of tangible objects such as these, lies in getting brands into the homes and hands of people. Subscribers look forward to receiving and keeping the items, or passing them on to family and friends."
