All the wooden sticks that you can buy in various board stores have a length of 25mm (also in our shop). This size is good in euro games, but the side of the track tile usually is about 23mm length. Therefore, especially for the 18xx games, we ordered wooden sticks with a length of 20mm. Currently, they are available in four colors: black, blue green and brown. If you need another color, let us know.
