Thank you for your response.
There was a white spot on the top of the back side that I think was from the sleeve insertion, although it is really faint. It might be a good idea to pay attention to it in the future.
Thank you again if you have a chance.
Thank you very much for your business.
I was worried about the safe arrival of the product, but I am glad to hear that there were no problems.
We look forward to working with you again when the opportunity arises.
