The authentic butterfly table tennis racket has the butterfly trademark metal logo on the bottom of the handle, and the JTTAA mother of several is clearly written below. Genuine licensed products have laser anti-counterfeiting labels on the packaging boxes. There is a "built-in password" below the label. After scratching it off, you can see the anti-counterfeiting password. As long as you enter the anti-counterfeiting password into the corresponding website, you can identify the authenticity! But it can only be checked three times, and it will become invalid after three times of checking.
