The Uni-Cup range is poly-lined on the inside for leak-proof performance, and can be used for hot or cold foods. They're easy to hold, and are great for soups and noodles, as well as fruit salad and yoghurt. The Ripple-Wrap™ Uni-Cups have a corrugated wrap that keeps hands cool and food warm, and are offered in brown kraft. One size lid fits all cup sizes.
