The difference lies in the cleanliness of the packaging and clothing lines.

"Boy" is the symbol of the British street brand London Boy. Its full name is "BoyLondon" and its clothing logo is an eagle trademark. The difference between genuine boys and high imitation boys are:

1. Outer packaging: The eagle trademark pattern on the genuine boy packaging bag is clear, while the eagle trademark pattern on the imitation boys is blurry.

2. Wrapping paper: The genuine boy wrapping paper is relatively thin and flexible, while the high imitation boy wrapping paper has no transparency.

3. Lines on the back: The lines of genuine boys are clean and tight, while the lines of high-imitation boys are messy.

4. Barcode: The barcode color of the authentic boy is darker, the font is slightly thicker, and the text on the bottom plate is lighter, while the high imitation boy is just the opposite.
