We added a limited supply of Flatbed Trucks to our Board Game Pieces Shop! They're made of wood and only available in black. In the photo, you can see that they hold 2 10mm wood cubes in the truck's bed. The 10mm cubes are slightly wider than the truck. Once these sell out, we'll encourage everyone to use our new line of plastic Flatbed Trucks which come in 8 colors and hold more cargo! 17mm meeple included for scale.
