Art set with a variety of watercolor pencils and oil pastels. - Set includes: Watercolor crayons, oil pastels, brush, sharpener - Design: Art by Christian Riese Lassen - Brand: Sumitomo Bank Art Museum - Storage case: Comes with a portable case It is unknown if the set can be used due to long-term storage. The crayons and pastels are likely fine, but I haven't tested them as they are new. Therefore, there is a possibility they may not be usable. Please refrain from purchasing if you have any concerns. Thank you for looking.
