This is a Blu-ray disc of Maria Callas. I purchased it at a used CD shop. I missed the chance to buy a player, so it's been in the same condition since I bought it. I believe it's a Blu-ray that includes concerts from Hamburg, Paris, and London, but please check the details written by the shop in the photos. Please understand this before purchasing. Thank you. I am also selling other Maria Callas items. If you purchase multiple items, I will discount them by 300 yen. I believe this is a hard-to-find item now. Thank you.
