Hello, it's my pleasure to serve you. The following is the method to distinguish the authenticity of doncaster wires: 1. Check the trademark: the trademark of authentic doncaster doncaster wire rod is "doncaster doncaster", with fine letter spacing and even and clear lines. Fake Philips wire trademark may have problems of blurred printing and uneven lines. 2. Check the model: the model and identification specifications of genuine doncaster doncaster wire are clear, and the characters and numbers are clearly visible. However, the model identification of counterfeit Philips wires is ambiguous or obviously different from the genuine ones. 3. Check the wire diameter and length: the wire diameter and length of genuine doncaster doncaster wire conform to the specification requirements, the wire diameter identification is clearly visible, and the length is accurate. However, there are errors in the wire diameter and length of the fake DONCASTER doncaster wire rod, and the wire diameter identification is unclear and the length is not accurate enough. 4. Check the packaging and identification: the packaging specifications of genuine doncaster doncaster wire rod are clear and definite. However, the packaging of counterfeit doncaster doncaster wire rod is rough and irregular, and there are typos and missing labels in the logo.
