All products come with an English installation manual. The manual includes color photographs to ensure a smooth installation process. For particularly complex steps, we provide links to video tutorials. If you encounter any difficulties, we offer online support to assist you.

If any issues arise after installation, we will provide appropriate advice to resolve the problem.

Since our products are not electronic devices and are highly durable, we do not specify a warranty period. If installed according to the manual and used within reasonable limits, damage or deterioration should not occur. In particular, our stainless steel products are more durable than aluminum ones, which is why we prefer stainless steel. If adhesive parts detach during use, please contact us. We do not charge for repairs, but we kindly ask you to cover the round-trip shipping costs.

For products with multiple specifications, we can suggest the most suitable option. If you are unsure which product fits your vehicle, please feel free to contact us. We may request photos of your vehicle for confirmation, so we appreciate your cooperation.

This is due to exchange rates. We use a fixed internal exchange rate, which may be adjusted if there are significant changes in the global economy. Additionally, some products for international customers may have different specifications from those sold in Japan. In some cases, international shipping fees are incorporated into the product price.
