Panasonic Water Purifier Installation Ring Packing PFP-H6135 Brand new, unopened, genuine product. I purchased this directly from the manufacturer to replace a packing, but it turned out to be unnecessary, so I am selling it. (Purchased approximately one month ago) The manufacturer's website is below (please check the compatible model numbers, etc.): https://panasonic.jp/consumables/products/PFP-H6135/shopping.pfp-h6135.html
