Tired of buying movement trays which are sold only at predetermined sizes? Are you looking for the opportunity to design your own movement trays which fit your army lists perfectly? If so, look no further! You can design your own Custom Monstrous Cavalry Movement Trays, for your mounted miniatures on the 50mm by 75mm bases, holding anywhere from one to fifteen models in a pattern of your design. The columns category refers to the number of models wide and the ranks category refers to the number of models deep.
