Thank you for viewing! This is a hard sleeve deco product made using resin. How about a cute trading card case to accompany your "oshi-katsu" (supporting your favorite idol/character) or "ota-katsu" (fan activities)? ■ Instant purchase is available. ■ Size: 69mm x 94mm (Card size that can be stored: approximately 63mm x 89mm) ■ Due to being a handmade product, there may be some unevenness or distortion due to polishing and coating. ■ During production, we take the utmost care, but dust (fibers) or air bubbles may inevitably get into the resin. ■ There may be initial scratches or fine scratches. ■ It does not have the same strength or quality as a mass-produced product. Please be careful as rough handling may cause damage. ■ If you have any questions, please feel free to comment. Thank you very much!
