Around June of this year, I purchased this new from someone here and used it for about a month, but it didn't suit me, so I'm selling it while it's still in good condition. There is no case. It will be packed in a bag or similar. Storage method: It was stored in a non-woven fabric futon bag in a chest of drawers. The cover has been washed. How it was used: I used another pillowcase over the cover, so it did not come into direct contact with my skin. Tempur Magniflex Nishikawa
