Very punctual and professional from start to finish
I purchased a pre-loved LV Bag and I wanted to play it safe! As it turns out, it is authentic and I could not be happier with the confirmation and authenticity certificate! Thank you!
They processed my request super fast!
they needed more photos and they were specific on the kind of photo.highly recommended site! will definitely use their service again. thank you so much!
My vintage Gucci bag didn’t have a serial number making it impossible for the average person to know if it was genuine. So happy for the outcome of my genuine handbag. Thanks again
It’s my 3rd time now using their service and I have to say their customer service is the best and got my certificates quite quickly. Highly recommend!
I was looking for a way to authenticate high quality vintage items and came across LegitGrails. So I sent them several items to authenticate and they were terrific. I had to send additional photos a few time but that gave me more confidence in them!
