Marshmallow bits added to Oreo O's.
Although unavailable for purchase in the United States, Oreo O's are still produced and readily available in South Korea, with boxes of this product being available for international purchase on eBay.
This cereal is no longer available outside of South Korea because Post and Kraft are no longer co-branding. Post owns the recipe to the cereal, while Mondelez, an American multinational confectionery, owns the rights to the Oreo brand name.
