Tube Toys are little toy vehicles created by London-based designer Oscar Diaz that are assembled from their own packaging. Inside each package are components like wheels and stickers that are inserted into pre-cut slots in the package.
The only part of the whole package that's discarded is the paper label on the outside. The rest of the pieces, which are all either recyclable or made from recycled materials, are used to assemble the toy.
The easy-to-assemble toys play off the fact that little kids often enjoy playing with the packaging as much as they do with the toy itself.
