Resin figures are primarily made from Polyurethane (PU) resin or Polystone. PU resin is preferred for high-end collectibles due to its superior toughness, flexibility, and ability to capture intricate details without being overly brittle. Polystone, a mix of resin and stone powder, offers a heavy, premium feel and is more cost-effective for larger statues, though it is more prone to breakage if dropped. Ensure your supplier uses non-toxic, eco-friendly resins that meet international safety standards.
