◆ This is a set of three educational books by Hama Omura. ◆ They have been stored at home for a long time, so there is some aging, yellowing, and wear and tear. The contents are free of writing, and I think you can read them comfortably. Please check the condition in the photos. Please understand that these are used items before considering a purchase. ◆ We may use recycled packing materials, but we will choose the cleanest ones possible and pack them carefully with care. ◆ No pets, no smoking.
