According to arrest warrants, the suspects were selling counterfeit versions of several brand names including North Face, Ugg and Hello Kitty.
"There's a lot of counterfeit stuff out there that looks real," fair visitor Catrinia Edgerton said.
She and her husband visited the fair in Raleigh from Dunn. They ended up buying items from the booth of a legitimate retailer.
Edgerton and her husband were surprised to hear a man and a woman were arrested from selling counterfeit merchandise.
"If I bought something that was supposed to be a certain name brand, and I got home and it was not, then I'd probably be upset," she added.
The vendors remain in the Wake County Jail.
"The state should be responsible for making sure vendors sell authorized merchandise," Jason Edgerton said.
The North Carolina Secretary of State's Office made the arrest Thursday.
According to arrest warrants, the items have a retail value of more than $10,000.
