These tiny trucks are actual erasers! They contain wheels that really work and the eraser parts come apart and can be put back together as a puzzle. The vehicles come in an assortment of colors and include trucks such as an excavator, dump truck and bulldozer. Please let us pick for you. If selecting multiples, we will be sure to provide the assortment. They're pretty tiny (only 1.25" long and .75 wide) so these are recommended for children over the age of 8.
