Thank you for viewing! This is a set of two 3m modular cables (telephone lines), 6-pin 2-core. It is printed with 60°C, 150V and 300V. *I do not know the details of the product. These are unused items stored at home, but there is some discoloration due to aging on the surface. Please note that I have not confirmed their functionality. Please check the photos carefully and understand the condition before considering a purchase.
