It depends on the figure, but my experience is that they are close to the 1/30 or 60mm scale of Britain's (and other manufacturers') matte figures. I have repainted a number of the standing Santa Claus - one of the basic figures available every year, and beginning in December 2020, making a pleated blue face mask from thin plastic strip and model ship rigging, to create a "COVID Santa" that I gifted as presents to friends and family. The resin sculpting of many of the figures and animals is quite good, and just needs batter repainting.
The deer family - buck as one piece, and the doe and fawn on another, also looks fine, but needs a more accurate repainting. Repainting the bases as brown/green lets them also be used in springtime dioramas.
