I have stored the item in a sleeve immediately after opening it. Please understand that this is a product from overseas before purchasing. Packaging: Sleeve + sandwiched between cardboard with water-resistant measures. If you would like to change the shipping method, please let me know in the comments beforehand. You can change it if you pay the difference. No price reduction, instant purchase is OK. I will offer a discount for combined purchases with other products. If you have any questions, please leave a comment.
