Copper prices have been rising since last year, resulting in frequent changes in quotations for copper products. This means the price of our copper-containing products is also unstable. To ensure product pricing, we will be introducing a validity period on our product quotes. Therefore, the validity period of unit price quotations for copper foil wire shielding sleeves, tinned copper braided sleeves, etc. is changed to 15 days. We apologize for the inconvenience caused by this move.
