This is for a pair of 0 gauge wheels as shown in the pictures. They have hard plastic wheels and metal axles. They are in very good condition, I don't think I ever used them. I've had them for many years. The diameter of the wheel is 28mm, the space between the wheels is 28mm, the thickness of the wheel is 5mm and the axle sticks out beyond the wheel by 5mm. I found it difficult to measure these wheels so the sizes are approximate. The flange seems to be slightly under 2mm. The thickness of the axle between the wheels is 5mm and 2mm sticking out from the wheels. The ends of the axles are rounded and not pointed. These are nice quality wheels, strong and well put together.
