Red Pen Oh My Brain Cognitive Picture Book Edition 1 & 2 Set

This is the Red Pen Oh My Brain Cognitive Picture Book Edition 1 & 2 set. Edition 1 consists of 15 main books, 5 types of teaching aids, and 1 supplementary book. Edition 2 is packed with content, including 15 main books, 6 activity books, and 1 supplementary book. Since it comes with teaching aids, children can enjoy reading while playing. It is a picture book set that can help with children's cognitive development and enhance their creativity. I recommend it to anyone looking for picture books that are good for brain development!!! I already have this at home, but I ended up with the exact same set, so I am selling it at a low price! I am a fan of Dr. Noh Gyu-sik, and I bought this set because I heard he participated in creating these books. I really enjoyed reading them. I looked it up, and the price for Edition 1+2 on Coupang is around 520,000 won! It is a brand new item with the box still unopened! I need to get rid of it urgently, so I am selling it at a low price. Negotiations are possible, so please chat me^^
