The. Best. Serving tray. Ever. The founder of Droog Design uses the simple physics (centrifugal force?) to produce a tray that is one-handed and spill proof. Beautifully balanced, it allows you to open doors, shake hands or serve the contents of the tray. But it also allows a freedom of movement because you know the drinks will not slop. Stainless folding handle with non-slip plastic tray. One of our favorite products.
