The Difference Between Ordinary and Platinum Silicone

We are confused why different sellers, different brands, they all sell silicone dolls. Why the price gap is so huge. The cheaper silicone sexdolls priced at $300-$600USD, the mid-high end sexdolls can be priced at $1500-$10,000USD. Regardless of the brand premium, brand features, or extra custom fee. There is an important factor- the material.
