Choosing the right material is critical for durability and realism. TPE (Thermoplastic Elastomer) is more cost-effective, softer to the touch, and highly elastic, making it popular for mid-range markets. However, it is porous and requires regular talcum powder application to prevent stickiness. Silicone is a premium choice; it is non-porous, heat-resistant, and offers superior detail retention for skin textures. While more expensive, silicone dolls are easier to clean and have a longer lifespan without the risk of oil leakage common in lower-quality TPE.
