Our Catalog Website: EvolMiniatures.com
All miniatures are made based on 3D models, and in same scale/size. What do you think about that?

Cool. I've been doing it for years for my own game minis.
Arion Games (https://www.drivethrurpg.com/browse/pub/667/Arion-Games) is doing this for decades and they have tons of different sets availabe. But competition is good for business, so good luck with your endeavor.
