# Miruko's Dam Cards ↑ We have many other dam cards available. Please tap here. The cards are stored in sleeve cases immediately after receiving them to prevent scratches and dirt. You can choose from three types of sleeve cases: plain, framed, and hologram star. For shipping, we sandwich the items with cardboard and strive to minimize curling and deformation during shipping.
