Thank you for viewing! During a big cleaning, I unexpectedly found a fourth set. (^^;) I am offering a Furutech FPX(CU) unplated wall outlet, along with an original outlet cover from Audio Mijinko as a bonus. This outlet uses phosphor bronze electrodes for high retention force and unplated construction for a natural sound reproduction. It can be used in various places, such as the main wall outlet or a power strip. The outlet itself can handle a maximum of 125V and 20A. The bonus outlet cover is an original from Audio Mijinko, featuring blue paint and electromagnetic wave countermeasures. ※ As you may know, legally, replacing a wall outlet in a house requires an electrician's license. If you do not have a license, please ask an electrician to replace it. However, a license is not required when incorporating it into a power strip, etc. It appears to be in relatively good condition with no noticeable scratches or stains♪ Please consider this opportunity! ʅ（◞‿◟）ʃ
