Tenpearl Biri Biri Guard GR-XB Leakage Breaker. I used it as a safety device for a microwave in case of a ground fault, until I could extend and install the ground wire. The included installation aid is unused. The instruction manual is included, but the plastic packaging is not. If you apply to purchase this and another Biri Biri Guard I have listed at the same time, I will sell both for 3399 yen. Please consider. The current price of this product is the lowest price. Please refrain from price negotiations. I decline price reductions requested through the price reduction request function, as most people do not purchase the item even after a price reduction. I am not listing this on other sites, so you can buy it immediately without a comment. Please note that this is a personally stored item, so please refrain from purchasing if you are a perfectionist. Thank you for viewing. Thank you for your consideration. * If the number of likes and comments exceeds a certain number, I will delete the listing and relist it after reviewing the price.
