I have stored this in a dark place after opening it. I have personally done some panel lining. Since I am not a professional, I would like to ask only those who are satisfied with it to purchase it. This is quite different from an unopened item, so please purchase only if you are satisfied with the photos. Also, to prevent any trouble, cancellations, returns, claims based on the condition, and refunds are not accepted after purchase. Thank you for your understanding. Regarding price reductions, I will gradually lower the price as I see fit.
