These are LEGO Duplo blocks that my child used to play with when they were little. They're considered good for a child's first blocks, but personally, I think they're fine up to around the lower elementary school grades. The characters are the three main characters from "Bob the Builder," which was on TV at the time. Please note that the crane part of the blue car can extend and retract, but the claw is missing and it comes apart when extended, and the string is frayed. These are primarily for young children to play with, so we ask that those seeking perfection or who cannot tolerate any scratches or stains refrain from purchasing. Please check the photos. Material: Plastic Gender: Unisex Character: Bob the Builder
