Tailor your inspection to the item.

Luxury Bags & Apparel: Genuine vs Fake Step-by-Step

  1. Chronology Check: Verify era-specific details (e.g., Chanel 2.55 has "Mademoiselle" lock; 1950s Hermès Kelly has rigid leather).
  2. Stitching & Hardware: Even stitches (8-10 per inch), heavy zippers engraved with logos.

Sneakers & Designer Goods: Authentication Markers

  1. Sole & Stitching: Clean glue lines, uniform threads.
  2. Tags: Correct fonts, heat-stamped details.
  3. Box Quality: Sturdy, no typos. Trend: Resale boom breeds fakes--use apps.

Electronics & Smartphones: Warning Signs & Serial Checks

  1. Leads/Terminations: Check for sanding/rework (AS6081 standard).
  2. Performance: Fakes pass basic tests but fail long-term (IDEA-STD-1010).

Holograms and Labels: Real vs Counterfeit Explained

Tilt Effect 2D/3D depth, color shifts Flat, static
Patterns Intricate, multi-layer Blurry, simplistic
Photos Needed 90-120 for capture Poor replication
