"Arithmetic Brain to Cultivate by Grade 3" "Arithmetic Brain Plus to Cultivate from Grade 4" "How Parents Can Improve Their Child's Japanese Language Skills" Masanobu Takahama "Arithmetic Brain to Cultivate by Grade 3" has discoloration on the edges and the top and bottom, but the inside is clean. The other two books are relatively clean. All are amateur inspections, but there are no markings. I apologize if I missed anything. Please refrain from separate sales. #MasanobuTakahama #Masanobu_Takahama #Books #Society/Education/Learning
