When evaluating polyresin figures, focus on material purity and density to ensure the product is not brittle. High-quality figures should use eco-friendly unsaturated polyester resin mixed with stone powder for a premium weight and feel. Pay close attention to the painting process, specifically the use of non-toxic PU paints and the precision of hand-painted details (eyes, skin gradients, and fine textures). For complex designs, ensure the factory uses silicone molds for high fidelity and offers modular assembly (magnets or pegs) to reduce breakage during shipping.
