Thank you for your continued use of our products.

We have recently received numerous reports that our products are being sold on various marketplaces at unreasonable prices or in conditions that deviate from official specifications due to unauthorized modifications or non‑genuine part replacements. Because sellers range from individuals to businesses, and because images alone often make it difficult to determine authenticity, we are facing challenges in addressing these cases.

Purchases made for the purpose of resale are strictly prohibited. If we confirm that a product has been resold—such as through listings on auction sites or other resale platforms—we may decline future sales to the customer involved.

All images published on this website are protected by copyright owned by our company. Unauthorized reproduction or use of these images is strictly prohibited.

To ensure that customers can purchase our products with confidence and enjoy them for many years, we require customers who have made a purchase to register their “Writing Chart” in order to receive after‑sales service.
