Not sure why this company is popular. Bought an LV bag for my wife on a business trip in Italy, directly from the LV store. Fast forward 2 years, she wants a different LV bag for Mother's Day, so she sells this bag. Her buyer gets it checked with Pro Authenticators and they tell her it's fake because the date stamp is too big!
My wife is horrified, takes the bag back, gets it checked by Pro Authenticators again to make sure, and they say it's fake again. My wife blames me, so we go to the nearest LV store and create some story about needing a repair. The store confirms it's authentic. My wife decided to sell with Rebag this week and they also said it's authentic.
Pro Authenticators just created a ton of unnecessary panic. I just bought a new LV bag for my wife for mother's day, and will have her check it with Pro Authenticators just to see what they say.
