Wooden multi-colored design blocks, perfect for shape recognition and color education. The blocks themselves have no noticeable stains, with only a little chipping on the corners. The string for pulling the box frayed less than a week after it was first used, and there's some blue staining, but it's securely attached to the box, and can still be pulled. There's a hole on the back of the box, so you could remove the string and thread a new one through. - Brand: Ed.Inter - Product Name: Design Blocks - Material: Wood - Color: Multi-color - Target Age: 3 years and up - Features: Perfect for shape recognition and color education - Accessories: Includes storage box
