„Think Eco.“ has been designed with the idea of packing a smartphone with only one piece of cardboard in its box. It’s a system of various folded cardboard strips, which gets its stability from the way it fits into the outer shell. The cartonboard strips are tucked into each other, thus providing a level in the middle where the phone is cushioned and therefore safe. Due to the special way of folding, there is space left above and below the phone to put in additional equipment. The phone can be removed easily from the box by unfolding the stopper on either side.
