The Vanishing Bin seems like a no brainer but the idea does look basic and sensible. By stacking brown paper bags nested on each other, the Vanishing Bin seems to be a great solution to keep things in order while taking out the trash when needed in an orderly fashion.

Each time a layer or a bag is full of garbage, one simply has to pull it out and then a new layer would be open to collect additional and further trash. So even though its layered composition may look excessive, it actually lessens the impact of your waste and reduces your runs throughout the house to collect and replace garbage bags.
