The product is a private listing of non-sport trading cards. This means that the cards being offered are not related to sports, such as baseball, basketball, or football. Instead, they are likely targeted towards collectors of various non-sport trading card series, such as Magic: The Gathering, Pokémon, or Yu-Gi-Oh. The private listing allows for a more personalized and exclusive selection of cards to be offered to buyers, rather than a general public listing that includes a wide range of cards for sale.
