This is the official *WINGS* concept book, released in 2017.
It contains a large number of photos.
*Please note that the bonus item is not included; the black envelope is empty.*
I have looked through it a few times and kept it carefully stored.
As shown in the images, there are some small marks or blemishes on the outer box—including those present from the time of purchase—so please only purchase if you understand and accept this condition.
Please purchase only if you are comfortable with a pre-owned item that has been in storage for a long period.
