does the subject want to ask, "What should I do if my friend gives me a lv half sleeve but I can't find out if it is fake?"? Observe labels and trademarks, observe materials and processes.

1. Real LV products have very fine labels and trademarks, and the edges of letters and patterns are very clear, and there is no vague and distorted feeling. Labels and trademarks are of poor quality, so they are fakes.

2. LV half sleeves are made of high-quality materials and exquisite craftsmanship. It is found that the material looks cheap and the technology is rough, so it is a fake.
