"One of a Kind" bags, or OOAK for short, are sample prototype pieces created by Dooney & Bourke but were never mass-produced. Since they are so rare, OOAK bags are not available for sale except through secondary marketplaces, like eBay.
Here are the known OOAK bags from the Pop Princess Collection:
Pop Princess Black Bucket Bag OOAK
The Pop Princess Bucket Bag was released in white. This black bucket bag was not mass produced, making this purse another Pop Princess OOAK.
