These multi-part models by Lost Kingdom Miniatures come with a decorative bases in either 40mm round, or 40x40mm square options. Shipwreck Screamers come in a basic group of 3, with no options.
 
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.
