Yocup high quality PET dome lids are designed to be compatible with Yocup’s paper hot & cold food containers. They are constructed without an opening to prevent leaks and spills when traveling with your frozen yogurt, ice cream, or even your lunch. This shape in particular is a round dome with a flat top which gives our customers the option to stack it when displaying it or for their customers to stack when carrying it out. It also makes more room for stacking up toppings and helps prevent foods from getting smashed.
