Gucci Classic Fit Men’s Dress Pants

Men’s classic fit Gucci dark khaki dress pants. Size is 31w x 32l. Made in Hong Kong of 100% cotton. These pants are a little worn and they have permanent seams that have been ironed into them. I looked over these pants at the stitching and tags and everything and it all looked very neat and clean, just looked a little worn. I think these are 4 years old. Anyways I did not know how to find a way to prove these are real Gucci and I didn’t know where to go to have someone look at them for me. I am selling these for a friend and he got them as a gift from his parents. He did say his mom never would have bought knock offs and she would have only bought these at Gucci. So take this all with a grain of salt. I am not guaranteeing these are authentic. But I think they are. If u can help me identify authenticity send me a message.
