美国采购需求：裸体女孩娃娃，硅胶男用性爱娃娃，硅胶成人娃娃出售，硅胶女用娃娃，sx娃娃，170厘米性爱娃娃

I'm looking for a cost-effective option for a lifelike sex doll around 170cm in height. It's crucial that the doll has a realistic appearance and feels good to the touch, as the primary goal is to ensure a satisfying user experience. I'm also interested in understanding the materials used and any customization options available. Additionally, please provide information on minimum order quantities, pricing, and any bulk discount options. I'd like to know about your production lead times and shipping details, especially if you have samples available for review. Looking forward to seeing what you can offer!
