Sanwa Supply Case for Surface Pro 4, 5, 6, 7, 7+

This is the PDA-SF3BK case from Sanwa Supply, compatible with Surface Pro 4, 5, 6, 7, and 7+.

I used it a few times, but it didn't suit me, so it's been sitting in the corner of my room ever since.

There are no particularly noticeable scratches, and I believe it's in good condition.
The original packaging is no longer available, so it will be shipped as shown in the photos.
