This is a campus set containing watercolors, crayons, oil pastels, colored pencils, markers, and more. I tested 3 of the markers at random, and they all worked. Please check the contents carefully. This is a used item, and some items are missing, so it is being offered at a low price. The box is also chipped. Please purchase only if you understand this. It is a box-shaped set with a handle. The case size is approximately 22cm x 31cm. I wiped down the areas that could be cleaned with alcohol.
