Between a fake bag and another original bag.. How do you spot a counterfeit product very well?

The resale market for luxury products is booming, as is the market for high-quality replicas. Seasons host Laura Jackson went to The RealReal's authenticity verification center to see if she could tell the difference between an authentic Hermès bag and a fake.

The prices of designer products have risen tremendously in recent years. For many, buying used luxury goods is the only way to get high-end fashion.

Hunter Thompson, director of authenticity verification at The RealReal, said that famous brands such as “Gucci” and “Louis Vuitton” are often subject to counterfeiting, and they put many bags through the verification machine to see the manufacturing method, and know the difference between the original and the fake. To spot a fake bag, Thompson explained: “You can pick it up, look inside it, touch it, smell it.

If you smell a chemical smell, that's usually a bad sign. "We pay a lot of attention to the feet of the bag," he added.

If its lines are clean, it is a “very good sign” that it is original. Whereas if it contains thread fasteners and adhesive, that is a sign that it is fake.

In the US, more than 40% of consumers say they have bought used clothing or accessories within the past year, according to research from Bain & Company, which means the volume of products that affiliates are having to verify for authenticity is growing rapidly.
