Thank you for viewing. This is a non-sale effector cover, a collaboration between BOSS and Ishibashi Music. Approximately 17cm x 13cm, unopened. Depending on the time, I will ship it on the same day or the next day via Yu-Packet Post Mini on weekdays. *I may cancel the transaction for those with many negative reviews, those who are slow to provide receipt confirmation, those with no transaction history, or those who have canceled in the past. Although it is unopened, it is still a used item. I do not accept any complaints or returns after purchase. Please understand this beforehand. #BOSS #EffecterCase #IshibashiMusicNovelty
