The Vario improves ergonomics of drinking beverages out of ps-cups by providing an ergonomic handle to hold onto and therefore prevents spilling and burning due to accidental dropping of the cup. The fact that the reusable and 100% recyclable Vario has an open bottom makes it fit a flood of different cup sizes, makes nesting possible and reduces material. Due to small wedges on the inside and a clamping effect whilst grabbing the handle it stays fastened to the cup without dropping down.
