These are used materials that my child used several years ago. They have pencil writing and red pen markings. They will be shipped as is, without erasing. Names will be erased with a marker or correction tape. They are in relatively clean condition. Thank you for your understanding of used items. Please refrain from cancellations after purchase. Thank you. Immediate purchase is OK. *Regarding Kumon materials, discounts for combined purchases cannot be offered due to weight constraints. We apologize for any inconvenience.
