Tokyo Interior if HOME Chair Pad, Seat Cushion

I found these cute and received them from the previous seller, but I haven't had a chance to use them, so I'm hoping someone else can.
The previous seller's description is as follows:
Used a few times by me.

Set of 2.
Purchased at Tokyo Interior and used for about 1 week on dining chairs.

No noticeable stains.
Since they were only used for about a week, I don't think there's any sagging.
I believe the original price was around 3,000 yen each.

I plan to pack them stacked.
Due to the large size and high shipping cost, please refrain from negotiating the price.
