Dear Valued Customer,
Notice of Product Price Revision
Thank you for your continued support and trust in our products.
Due to the significant increase in the cost of tungsten, our primary raw material, as well as rising prices of auxiliary materials and other related costs, maintaining our current pricing structure has become increasingly challenging. We have undertaken various measures to improve operational efficiency and reduce costs.
Despite these efforts, we have reached a point where it is no longer possible to absorb the continued cost increases through internal measures alone.
To ensure the continued supply of high-quality products and maintain a stable and reliable service to our customers, we will revise the prices of our products as detailed below.
We understand that this adjustment may cause inconvenience to our valued customers and sincerely appreciate your understanding and continued support.
