Thank you for viewing. These are number blocks used in elementary school. The blocks are magnetic. There are scratches and dirt from normal use. The black marks have faded with an eraser, so they might come off completely with some effort. Please consider this item as used by an elementary school student. All blocks have names written on them. The name in the second photo has been blacked out. To reduce shipping costs, the box will be opened for shipping. Thank you for your understanding.
