Yeah. I hear ya. Completely legit. I was kind of wondering how I could make a person feel comfortable with it and haven’t come up with a plan yet. Lol
In the photo there’s a card. You could call the guy at Gobi, mention that you have the certificate and ask how best to use it. If he says you’re on glue & they never gave out the certificate then don’t buy it. If he gives you the name of a distributor to buy from that will Honor it then you know it’s real.
