Recently, global copper prices have continued to rise, which means that the prices of our copper-containing products are also unstable. To combat this, we have decided to introduce expiry dates on our product offers. Therefore, for example, the unit price quotation validity period for Copper Foil Wire Shielding Sleeves,EMI Tinned Copper Metal Braided Cable Sleeve, etc. is changed to 15 days. We apologize for the inconvenience caused.
