When sourcing high-end figures, prioritize PVC (Polyvinyl Chloride) or ABS (Acrylonitrile Butadiene Styrene) for their durability and detail retention. For premium collector editions, Cold Cast Resin or Polystone offers a heavier, more realistic texture. Pay close attention to the painting process (skin tone gradients, eye decals, and shading); high-quality figures should have no visible mold lines, paint bleeding, or air bubbles. Ensure the supplier uses non-toxic, eco-friendly pigments that meet international safety standards.
