This is a first-edition bonus item from volume 10, which was just released in South Korea on August 25th. It's a hologram specification and made of sturdy material, similar to thick card stock. After receiving it, I immediately stored it in a sleeve and a rigid case. However, there may be initial scratches or scuffs, which are common in overseas products. Please only purchase if you understand and accept the nature of overseas goods. Upon purchase, I will ship it within 24 hours via anonymous shipping, packaged with a sleeve + rigid case + waterproof measures. Direct purchase is welcome.
