Tennino is a cardboard flat-pack ping pong table, made by German designers Kickpack. Perfect for the occasional table tennis player, the game is intended to be an alternative to the big, bulky, and less portable permanent versions in plastic, and would be great for home or even the office. And of course, it’s made of recycled materials, making it more environmentally friendly. The ping-pong table is available on the Kickpack site, where you can also find a cardboard table football game. Tempted? Us too.
