While we strive for accuracy in product images, specifications, and pricing, actual colors may differ due to display environments.

We recommend installation by a qualified mechanic. We are not liable for defects or accidents resulting from self-installation.
Products with manufacturer warranties are subject to each manufacturer's warranty terms. Deterioration from long-term use, normal wear, or customer mishandling may not be covered.
Products marked "for racing use only" or "not for public road use" must be used in compliance with applicable laws. We bear no responsibility for accidents or violations arising from use on public roads.
Used or rebuilt products are sold with the customer's acknowledgment of the condition described for each item.

Article 4 (Formation of Contract)

A sales contract is formed when the customer completes the order process and we send an order confirmation email.
We may cancel or rescind a contract even after formation in cases such as stockouts, pricing errors, payment denial, or suspected fraudulent orders. Any payment received will be refunded.

Orders are typically shipped within 1–3 business days after payment confirmation (exceptions noted on product pages or by email).
Orders placed on weekends, holidays, or our company holidays will be processed from the next business day.
Delivery may be delayed due to natural disasters, traffic conditions, or customs clearance.

Article 7 (International Shipping and Customs)

Where international shipping is available, availability, methods, and fees vary by region.
Customs duties, import taxes, and customs fees are generally the customer's responsibility (charged by the carrier or customs authority).
International returns are generally not accepted due to customs and shipping costs (initial defects will be handled individually).
