I was obsessed and read them all when I was in elementary school! So there are some minor scratches and dirt, please consider carefully before purchasing. They are super interesting! I recommend them! I kept them in a sunny spot, so the spines have faded TT I'd prefer to sell them as a set, but I'm open to selling them individually! Price negotiation is also possible, so feel free to ask!
