Shichida-Shiki Print B vol. 10, a set including characters, numbers, and intelligence. The contents were copied for use, so there are no markings. All 24 sheets of characters, numbers, and intelligence are complete, and answers are included. They have been separated, so they can be copied. The cover shows signs of use. This is a used item, so it is not in the same condition as new. My child studied with this set when they were in their final year of kindergarten, after purchasing it on Mercari as a trial of Shichida-Shiki. I was worried about starting with C, so I tried vol. 10 of B, and it went well, so we continued with C and D. I think it's a good level and amount for a kindergarten trial set. It's from 2017, but I don't think there's been any change in the trends of kindergarten studies since then, so there's no problem.
