Collection Sleeve Set with Various Designs - Design Sleeves: Includes multiple design sleeves. - For Collection: Includes sleeves for collection purposes. - SWIMMER: Includes design sleeves from the SWIMMER brand. - Size: Each sleeve is suitable for standard card size. Thank you for viewing. Some are new and unopened, while others have been opened. I used these for K-POP trading card cases. I collected various sleeves, but I no longer use them, so I am selling them as a set. Please take a look at the images and consider purchasing if you understand. Thank you for your consideration.
