Unused, New Airweave Mattress Topper & Fitted Sheet, Single Size, 2-Piece Set

Airweave Mattress Topper (Shoulder Comfort) Single
Fitted Sheet Gray Single
This is a 2-piece set.

I purchased this about 1-2 years ago from Japanet with the intention of using it, but due to various circumstances, I haven't had the opportunity. Since it seems unlikely I'll use it in the future, I'm putting it up for sale.
I also purchased the sheet, so I believe the set cost around 140,000 yen.

It is new and unopened, but has been stored at home.
It was stored indoors in its box. There may be areas that appear white due to light exposure, but there are no particularly noticeable scratches, dirt, or damage. I opened the box for inspection for this listing, but the items themselves have not been removed from their bags.
The original box has scratches, tears, and dirt from when it was brought into my home, as the entryway was narrow. Please check the images. Thank you for your understanding before purchasing. The sheet arrived separately but will be shipped together.
Please refrain from purchasing if you are concerned about minor details.

Shipping will be via Sagawa Express, with the shipping label attached directly to the original box.
(For residents of Okinawa, remote islands, or Hokkaido, or if you wish to change the shipping method, there will be an additional charge. Please comment before purchasing.)
I will apply tape to any torn areas.

At this time, I am not considering selling items separately or lowering the price. Please consider it at the current price.
Immediate purchase is welcome.
