These are materials subscribed to in the 2023 school year for the kindergarten middle group (4 and 5 year olds). Some parts haven't been used, but most have been used as they were learned in kindergarten. They are relatively clean, but there are some folds, so how about it for those who want to try them out? This is the second half of the year, from October, November, December, January, February, and March. Due to the thickness and weight, I can only send them in two parts, so those who want to purchase a full year's worth should make separate purchases. There is a name written on the spine, so I will cover it with a black marker before shipping.
