How to distinguish the true and false red shell engine oil

1. Put the oil vertically, and see a label on the oil bottle cap that says "Shell Lubricating Oil", which is printed with color-changing ink. The color of the text will change with the change of viewing angle.

2. Please pay attention to your friends! The "authentic" label disappears after soaking in water and reappears after drying.

3. Carefully uncover the anti-counterfeiting surface from the red arrow on the label. Laser holographic film: This anti-counterfeiting method is quite common, and many manufacturers use this kind of laser holography. After uncovering the label, you can look at the back of the label from different angles and flash the rainbow shell logo.

4. The16-bit shell security code is arranged in the upper and lower lines. The number of the logistics code under the security code should be exactly the same as the number under the unique bar code outside the security label.

5. Unique barcode: the official name is "variable barcode". In fact, each shell anti-counterfeiting label has a unique non-repetitive bar code, which means that there will be no duplication under any circumstances, even in the same box.

6. Miniature text: The naked eye looks like a line. Under the magnifying glass, you can see that this line is composed of miniature "shells".

Enter the number according to the prompt (please note that it is an anti-counterfeiting number, not a logistics or management code) to immediately verify the authenticity of the product. Just enter the 16-digit anti-counterfeiting code according to the prompt language.

8. The label on the second floor has a red "shell" under ultraviolet radiation. 3. At present, Shell Lubricant 4L has telephone anti-counterfeiting inquiry, but all 1L engine oil products have no anti-counterfeiting inquiry. ?
