These colourful plastic cupcake cups, called Sweet Cakes, are 70 cm in diameter. Apparently they are meant as all-purpose containers, and can even be bought with a pillow for your cats to nap on—first take the toddler and the water out though. Designer Beerd van Stokkum sells them on his own website in most colours of the rainbow for 150 euro a piece.
