This is the DVD of BTS' "2021 MUSTER SOWOOZOO". It is not Blu-ray. I purchased it when the DVD was first released. I haven't used it and have kept it at home for several years. I have not checked the operation. The box and DVDs have dirt and scratches. Also, one of the tabs that holds the DVD is broken. The postcards are in clean condition with no stains, as I only took them out when I purchased and inspected the item. The photobook has some bent corners, but the contents are clean and in good condition. Please check the images for the condition described above. If you have any questions, please ask in the comments. Please purchase this item if you understand that it is a used item.
