What materials are commonly used in Demon Slayer comic and online game model toys, and how does this impact their quality and price?

Common materials include PVC, ABS plastic, and occasionally die-cast metal. PVC is prevalent for figures due to its affordability and moldability, while ABS is used for structural parts requiring rigidity. Die-cast is rare but adds weight and a premium feel. Higher-quality PVC and ABS, along with intricate paintwork and articulation, increase both the quality and price.
