Here is a step-by-step inspection guide from a professional appraisal perspective to help you identify the authenticity of Louis Vuitton side backpacks (such as the classic style **Pochette Accessoires**, **Multi Pochette** or new side backpacks).
—
### **1. Check the material and presbyopia pattern**
– **Authentic features**:
– **Monogram Canvas**: LV classic presbyterian material is made of canvas coated (non-dermal leather), which feels slightly soft but tough, with clear surface texture and even graininess.
– **Symmetry**: Presbyterian patterns (four-leaf flowers, LV letters) are strictly symmetrical on both sides of the wrapper body, and fakes may have pattern misalignment or proportional imbalances.
– **Color comparison**: The original presbyopia background is beige (non-pure white), the pattern is dark brown, and the imitation may be yellow or gray.
—
### **2. Observe the wiring and sewing details**
– **Sewing crafts**:
– The authentic product uses ** wax thread**, the color is golden yellow (some styles may be beige), the stitching is neat, the angle of inclination is consistent, and there is no loose thread tip.
– The sutures at the joints of the handle and the packaging body, such as the stress-bearing parts, will be reinforced, and the stitches will be fine and even.
– **Edge Handling**:
– The edges (such as leather piping) should fit smoothly and without glue overflow or burrs.
—
### **3. Hardware identification**
– **Materials and lettering**:
– Genuine hardware is ** brass gold-plated/silver**, which is thick and textured, with clear lettering and sharp edges.The imitation may be light and the coating may fade easily.
– **LV Logo Engraving**: The letter “**L**” has a short bottom and a short horizontal line, the “**V**” has a sharp bottom, the “**O**” is a perfect circle, and the “**N**” is wider and the two ends are square (see the figure).
– **Zipper**: LV commonly used **YKK** or **Riri** zippers, with clear lettering on the pull, smooth and no lag.
—
### **4. Leather details and imprints**
– **Heat Stamp**:
– The internal standard imprinted font is clear, the letter spacing is evenly spaced, and it complies with the LV brand font specifications (for example, the “**O**” circle, and the end of “**S**” in “**Paris**” is slightly sagging).
– The authentic imprinting is moderate, and the imitation may be too deep or blurred.
– **Leather smell**: Genuine vegetable tanned leather has a faint natural leather fragrance, and fake products may have a pungent chemical smell.
—
### **5. Serial number and date code**
– **Position**: The date code of the side backpack is usually hidden in the following locations:
– The inner bag side suture
– Back of small label on the inside of the body
– **Format Rules**:
– 2007 years ago: **2 letters + 3 numbers ** (such as **FL102**)
– After 2007: **2 letters + 4 numbers ** (such as **SD2109**, which means production in the 21st week of 2019)
– **Note**: The encoding must be clear and neat, without manual scratches.
—
### **6. Lining and accessories**
– **Line material**: The authentic lining is mostly **brown microfiber cloth** or **canvas**, with a delicate touch, and the LV logo print is low-key (some new models may use red velvet cloth).
– **Dust Protection Bag**: The authentic dust bag is beige, the fabric is thick, the LV letters are light and the edges are blurred, the imitation may be too white and the print is rough.
—
### **7. Packaging and Accessories**
– **Shopping voucher**: The authentic product will come with invoices, dust bags, and cartons (mostly light brown environmentally friendly boxes in recent years), but high imitation may forge a full set of packaging, and comprehensive judgment is required based on other details.
– **Instruction**: LV does not provide paper instructions. If you find that a “maintenance manual” is included, you should be vigilant.
—
### **8. Professional appraisal assistance**
– **Online Tools**: Use **LV official website** or **Enttrupy** and other AI authentication apps to scan material details (pay required).
– **Offline Channel**: It is recommended to pass the **LV counter** (some stores provide unofficial appraisal) or the **third-party luxury appraisal agency** (such as China Inspection and Reebonz certification).
—
### **Summary of common fake flaws**
– Presbyopia pattern is yellow or has too strong reflection
– font errors in hardware engraving (such as the bottom of “V” is round and blunt)
– The stitching color does not match the material (such as white thread)
– Date code format error or position deviation
—
**Precautions**: High imitation packages may pass some identification points and must be judged in detail.When purchasing, formal channels are preferred (official websites, counters, authorized retailers). Second-hand transactions are recommended to use platforms with appraisal guarantees (such as The RealReal and Vestiaire Collective).
