I love this cool invention. I am unsure of just how sustainable an product design like this would be but I will say it is a great way to reuse cardboard! I would like to think that this would work perfectly if you were to sell those tiny flowers and herbs like in the garden center of Home Depot or Target. The truth is that when we buy a plant from a store we end up taking it right out the plastic pot and throwing it away so that we can put our plant in the ground. Think how much more practical it would be if we used cardboard, which would be biodegradable, and then threw it away. Great product design, really great.
