We have confirmed the product.
Thank you very much for your kind attention.

I don't mind, but there was no extra sheet.
Also, I had the impression that it was not an extra, but just a normal one, a piece of cardboard to keep it from folding.
I don't think you should expect any extras.
The product arrived safely.
