As one of the world's most well-known luxury brands, Louis Vuitton's briefcases (especially classic styles such as Taïga Leather or Monogram Canvas) are highly sought after for their exquisite craftsmanship and value retention, but they have also become the hardest hit area for counterfeit products.Here is a professional-level certification guide covering every detail from appearance to craftsmanship:

---

Step 1: Check the material and leather

1. Monogram Canvas
   

• The surface of genuine canvas has the most delicate grainy feeling, which is slightly astringent but smooth, and imitations are usually too smooth or rough.
  
• Pattern clarity: The edges of the genuine Monogram pattern are sharp, symmetrical and without breakage (for example, the "Four Leaf Flower" pattern next to the LV letter should be fully aligned).
  
• Coating color on the edges of canvas: The authentic product is dark reddish brown (thinning over time), and the imitation product may be orange or shiny.
  
  
• Leather Part
  
• If it is Taïga cowhide (commonly in men's briefcases), the authentic leather is natural, soft but firm, and the imitation may be stiff or over-embossed.
  
• Edge dyeing: The genuine leather has a uniform beeswax-colored edge seal, and the imitation may overflow or be too light in color.

Step 2: Hardware identification

1. Metal lettering
   

• Genuine hardware (zippers, locks, rivets) lettering clear and sharp , the font is Louis Vuitton customized font, for example:
  
• "O" in "LOUIS VUITTON" is close to the perfect circle, and the imitation may be elliptical.
  
• The strokes at the bottom of the word "PARIS" are slightly thicker.
  
• Zipper head: genuine multi-purpose YKK zipper or brand customized zipper (such as EPI series), the zipper teeth are smooth and burrs-free.
  
  
• Metallic color and weight
  
• Genuine hardware is matte gold or dark gold (depending on the series), and the imitation may be too bright or yellow.
  
• Lock opening and closing sound: The authentic spring mechanism is smooth and silent, and the imitation may have metal friction sound.

Step 3: Sutures and Structure

1. Sewing process
   

• Genuine use wax thread, the color matches the leather/canvas (such as the golden thread with Monogram series), the pins are tilted and the spacing is consistent (about 5-6 pins per inch).
  
• Frequently Asked Questions for Imitation: The thread tip is exposed, the pins are tilted or the use of cheap nylon thread.
  
  
• Inclusion structure
  
• The authentic briefcase can maintain a crisp shape regardless of whether it is full or not, and the bottom corners are reinforced.
  
• Interior lining: The classic model uses brown/red microfiber cloth (Alcantara material), and the imitation may use ordinary canvas.

Step 4: Serial number and date mark

1. Position and Format
   

• The serial number is usually located at the seam of the inner bag or on the lateral leather mark, and consists of 2 letters + 4 digits (such as FL2153).
  
• The first two letters represent the origin (such as FL is France and TH is Spain).
  
• The last four digits: 1-3 digits are the number of production weeks, 4 digits are the year (changed to the number of weeks after 2007, and 3-4 digits are the year, such as "1121" that is the 11th week of 2021).
  
• Note: The packages before 1980 have no serial numbers and gradually became popular after 2000.
  
  
• Embroidery details
  
• The authentic font is a brand-specific font, the number "6" is curved at the top, and there is no hook at the bottom of "9".
  
• Common errors in imitation products: font blur, position offset or logical error (such as "0224" represents the second week of 2024, but the current year has not arrived, it will be fake).

Step 5: Packaging and Accessories

1. Dust bag and box
   

• The authentic dust bag is made of off-white cotton, with a light gray LV logo printed with neat lines.
  
• The imitation may use cheap non-woven fabrics, and the logo is roughly printed.
  
  
• Certificate and Receipt
  
• Louis Vuitton has canceled the paper certificate since 2019 and only provides electronic purchase records.If the seller provides a "certificate", you need to be highly vigilant.

Advanced identification skills

1. Ultraviolet rays
   

• The authentic Monogram canvas will show the weakest red fluorescent spots under ultraviolet light (anti-counterfeiting technology), and imitations do not have this feature.
  
  
• Brand Font Library Comparison
  
• Use a magnifying glass to observe the "Louis Vuitton Paris" on the leather mark. The authentic letter "L" is short in horizontal and long in vertical direction, and the "S" narrows up and down.

• ❌ The price is too low (the average price of genuine second-hand briefcases is above $2,000)
  
• ❌ Hardware engraving is not clear
  
• ❌ The color of the lining line does not match the outside
  
• ❌ The serial number cannot correspond to the production year (such as the "MI" code represents France, but the numbers show that production is in 2023, and the French factory has been closed)
