This is a set of 50 CDs, including those by Nogizaka46. 48 of the CDs are singles, and the other 2 are albums, so there's plenty to listen to. They are new and unopened, but please purchase only if you don't mind them being stored at home. Regarding shipping, I plan to use simple packaging and a recycled cardboard box. Please understand that I cannot offer refunds or returns for any damage that may occur during shipping. Thank you.
