It is comfortable to finish installing without problems. I was in trouble because I did not put it in the home center etc, but I was really saved by Monotaro san. I am going to rely on shops that are amazing stocks in the future.
The sliding door of the dining room that opens and closes frequently does not move smoothly, and as a result of examination the car has been cracked and chipped in aged deterioration (used for 17 years). I immediately hit several home centers and hardware shops, but I was told that it was not possible to order unless it was 50 units. When I looked it up on the internet, I found that "Monotaro" sold 2 packs of packs, which was very helpful.
