A limited unique item is a type of limited hat, gear or face that has a limited quantity of stock. Each copy has a unique serial number (e.g, #125 out of 200). A limited unique item will be available for purchase for a set amount of Robux until it is sold out. After it has been sold out, users with a Builder's Club membership can trade them for other items or re-sell them for ROBUX. Although a user with a free account has bought a limited item, they cannot trade or sell them.
Criticism
Scammers may scam other people for overpriced Limited Unique items just like regular limited items, which led to moderate criticism.
