Shichida Educational Institute Correspondence Course for Preschoolers This is a binder summarizing advice for the 11-month to 1 year 10-month age group. I received this from someone else. My child has grown, so I am now selling it. It was very educational (*^ω^*)!! Regarding the condition, the curriculum pages have come loose. Please check the photos. I don't think it's a major issue for reading, but there are some creases, dirt, and discoloration. This is a used item, so please only consider it if you understand this. m(_ _)m!!
