Instant purchase is OK. Everything has been opened. 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, which is a feature of Mercari, because they get buried among other products and I cannot confirm them. Please understand. Therefore, if you wish to negotiate a price reduction, please make a comment with your desired price. If you are considering purchasing multiple items, please use the bundling feature, as it will allow me to respond more smoothly.
