These multi-part models by Lost Kingdom Miniatures are designed to fit on either a 35x60mm oval base, or a 25x50mm square base. 
 
We do a decent removal of all of the supports from the printing process that we can without spending too much time, but we recommend you doing your own inspection of the models for anything that we missed.
 
We do not provide bases with any any of our prints, unless a full decorative base is part of the print.
