This is a set of Grimm's Arch Rainbow Extra Large (the largest size) and a semi-circle disc. ① Semi-circle disc Brand new and unopened. Purchased from the official shop in the spring and stored at home. ② Arch Rainbow It has some dirt on it because it was played with frequently from the age of 0. The stickers have been removed to prevent accidental ingestion. Purchased from a department store in Tokyo. I am selling these because I have too many building blocks at home and am decluttering. As shown in the last photo, building a tower is a typical Grimm's play style. Therefore, please refrain from purchasing items separately. Educational toy, building blocks
