A set of ten cups is available. I don't know how they were obtained. My family kept them at home. They are not arranged in the order specified in the instructions. As shown in the photos, the instructions are covered in stains and are taped to the box. There are also tape marks on the front of the box. I checked each cup for cracks, but I am not a professional, so there may be oversights. When shipping, I will add extra padding to fill the gaps. Please also read my profile.
