The London-based design studio Mash Creative has collaborated with the Design Museum for their latest collection of varied goods. Their “State of the Obvious” collection is a hodgepodge of items including iPhone and iPad skins, marker pens, USB sticks, travel card wallets and keyrings. And like the title suggests, each piece of the collection tells you exactly what it is, just in case you didn’t already know. Products range between $5 (£3) for the travel card wallet to $33 (£20) for the iPad skins.
