This is for one set of 2 feet to hold your monorail pin board. One set is enough for a standard sized monorail. If you choose to add more cars to your monorail, you may want to purchase more than one set of feet.
Black is the recommended color for your feet so they blend in to the rim of the board but you can select any color on the color menu
Not compatible with any other boards not mentioned. Does not come with a pin board, that must be added separately.
