Brain Sleep Portable Neck Pillow - Used for approx. 10 minutes

Thank you for viewing.
I am selling this Brain Sleep Portable as I have two of them.

I actually tried sleeping with this one at night, but it didn't quite suit me.
I only slept with it for about 10 minutes.
(I used a thick pillowcase, so it was not directly touched.)
After that, I stored it in a paper bag inside my suitcase.

When I exposed it to sunlight, I noticed a round shadow-like stain on the back.
It's only noticeable in bright light.
I did not spill anything on it, and since it's a perfect circle, I believe it was present from the beginning.
Please understand.

Since I tried this one more than the other, and I've already discarded the bag and band, I'm offering it at a slightly lower price.
I will ship it folded into the square shape shown in the 4th photo.

I don't use a neck pillow on flights, but
since it can be shaped in various ways, it seems useful not only on planes but also in hotels at your travel destination.

Shipping will be on December 28th.
Please understand.

Thank you.
