This set will include miniatures/terrain/printed pieces that failed during print or had imperfections rendering them unable to be sold as full priced items.
You can use these like I do to practice painting (I still have a lot to learn) before tackling your better miniatures, or to test different paint textures or use as scatter. Each set generally comes with around 10 miniatures/terrain of various sizes from small to large/huge!
No set will ever be the same. As the set already comes with broken pieces, there will be no returns offered.
