FURminator Genuine Product The manufacturing number is written on the blade. I am selling this because my Siberian cat doesn't like it. I used it for about two weeks, but I don't think there are any scratches or blade chips. Please check the photos. It removes a lot of hair! It's a little scary how much it removes. *Please refrain from price negotiations. 【Effective Hair Removal】 The FURminator is designed specifically for long-haired cats and effectively removes loose hair. 【Patented Technology】 With its unique patented technology, it is possible to thoroughly remove loose hair from the roots.
