I am satisfied that I want to maintain the current quality because it is a part that has been used for many years.
One point, it is impressive that the response when you contact the manufacturer directly, was because it was an individual inquiry or it was too dry (cold).
I was disappointed just to trust in quality.

Previously, things purchased elsewhere will cost more than 30,000 yen, which was also prepared at a certain price this time, but I can be purchased here with less than one third here and I am satisfied with no particular problem even if using it.
