The revolutionary advancements in the torso sex doll manufacturing industry are inseparable from innovative developments in materials science. Recent breakthroughs in polymer materials have made the skin texture of the new sex doll virtually indistinguishable from real people, even capable of simulating the finest pores and blood vessels. Laboratory-developed composite silicones possess self-healing properties, allowing minor scratches to heal automatically at room temperature, significantly extending the product's lifespan.
