Could you please tell me the procedure for requesting repair or modification of the product?

When you request repair or modification, we will first need to receive the product and check its condition at our company.
(Please note that we may not be able to repair or modify products depending on the year of manufacture.)
Requests for repair or modification can be submitted through the designated form.
At that time, the serial number of the product will be required.
Please make sure to check the serial number on the label attached to the product before contacting us.
