I was gifted one of your Manna cups from a local church, ladies' group. I was taking Chemotherapy for Leukemia and lymphoma cancer, Non-Hodgkins. It was wonderful to have a cup that would stay so cold during the long days at the cancer center, chemo makes you very thirsty. I have used my cup every day since receiving it. I accidentally knocked it over recently, unfortunately the lid where the cover cap screws on, snapped off. I was heartbroken. I tried gluing it back together but it did not work...
