This is a special "Justice" coaster featuring Attack on Titan and Sapporo Black Label. It was a novelty item included when I purchased Sapporo Black Label, but I'm selling it because I don't use it. It was attached to the box with double-sided tape, so there are slight cardboard marks on the back, but it's new and has never been opened. Shipping will be by regular mail (no tracking or insurance). If you prefer anonymous shipping, I can accommodate it for an additional ¥100, so please comment if you'd like that option.
