Anyone with kids knows that they sometimes prefer to play with the packaging than the actual toy. These clever toy vehicles by London designer Oscar Diaz are assembled from their own packaging.

Each Tube Toy comes with components like stickers and wheels inside a cardboard tube that becomes the body of the car, fire engine, train or tractor, with pre-cut slots for easy assembly. Only the paper strip round the outside is discarded and all components are recycled or recyclable.
