Instant purchase is OK. The regular edition has been opened, but the others are unopened. I have stored them in a dark place after purchase. I will wrap them in cushioning material for shipping. I cannot respond to price reduction requests using Mercari's feature because I cannot confirm the requests as they get buried in other products. Please understand. Therefore, if you would like to negotiate a price reduction, please comment with your desired price. If you are considering purchasing multiple items, please use the bundling feature for a smoother transaction.
