Oslo paper is a type of paper that is commonly used by elementary students for arts and crafts in the Philippines. It is a rough 9" x 12" piece of thick white paper that is known for its sturdiness and thickness, making it perfect for water-based paint and felt-tip markers. It is also used for other art materials such as pencils, crayons, and pastels. Oslo paper is sometimes referred to as bond paper. It is available in reams of 250 sheets and has a basis weight of 100 gsm.
