The blood is stored in two hermetically sealed small ampoules, held since the 17th century in a silver reliquary between two round glass plates about 12 cm wide. The smaller ampoule (of cylindrical shape) contains only a few reddish spots on its walls, the bulk having allegedly been removed and taken to Spain by Charles III. The larger ampoule, with capacity of about 60 ml and almond-shaped, is about 60% filled with a dark reddish substance. Separate reliquaries hold bone fragments believed to belong to Saint Januarius.
