These are stair mats I bought on Amazon for around 6000 yen. I bought them because my feet were cold, but due to a family mix-up, I ended up exchanging them for something else. I've only used them for about two weeks, so I think they're still in good condition, but please refrain from purchasing if you are overly concerned about used items. No claims and no returns. I've removed the dust that can be taken off with a vacuum cleaner. I don't have any pets. I've included the Amazon page for reference, but it seems this pattern and size combination is no longer available.
