All CRES products are manufactured in Japan. It was an arduous process of having many prototypes sent from Japan, and having many adjustments made, and reexamining those new prototypes. It takes a lot of time and money, but this repeated scrutiny was necessary so that we can deliver products that we are completely satisfied with. Our product development team trusts in Japanese manufactured products. This is because they have the technology and assurance to answer all of our requests.
