Rokuhan Z Shorty Features: 1/220 sized micro railway model
Z Shorty is a Z gauge car model that has been default in about half the length of the car. Although it is a deformed model, the attention to detail is still intact.
By combining the power chassis and trailer chassis with a vehicle sold separately, it can also be run like a regular Z-gauge vehicle.
