I am selling this item because I accidentally purchased the wrong one. It is a brand new, unopened item that arrived today. I purchased it at Bic Camera for 15,000 yen. The 6th image, the delivery receipt, contains personal information and cannot be included! I've included it to prove the recent purchase!
