The refill will be packaged with a hard case or thick cardboard and made waterproof. Although it is new and unused, please refrain from purchasing if you are sensitive to the condition, as it has been stored by a private individual. Immediate purchase is welcome. We will offer a small discount if you purchase other items at the same time. We will package with thick cardboard for 3 or more items. treasure HYUNSUK JIHOON YOSHI JUNKYU JAEHYUK ASAHI DOYOUNG JEONGWOO HARUTO JUNHWAN
