Zelex is one of the best brands of silicone sex dolls. If consumers have the opportunity to visit Zelex’s studios and factories, they will be shocked, Zelex’s product quality, talent pool, craftsmanship, and workshop management are all industry benchmarks.
Currently, Zelex has updated its doll heads to include the movable jaw and unique makeup designed for heads with an oral structure. Additionally, they have upgraded their hair transplant technology and enhanced the eyes to be bright and beautiful, making these doll heads more realistic and practical.

Zelex SLE Series
The acronym “SLE” stands for Safe, Less-vinyl, and Elastomer.
Through material formulation optimization and production process improvements, SLE material reduces vinyl content while maintaining its eco-friendly properties. Sex doll heads made from this material show improved softness and durability.
Tests have confirmed that this series meets safety standards and has passed multiple non-toxic certifications. It fulfills customers’ expectations for health, comfort, and durability in sex dolls.

Non-Customization
Zelex SLE series sex doll heads are produced using a standardized production model. The main design is based on mainstream aesthetic preferences for facial features.
This non-customization strategy simplifies the purchasing experience by eliminating the complexity of multiple options. At the same time, standardized production ensures that the products maintain consistent specifications and stable quality.
The mass production model reduces the manufacturing cycle per unit, improving logistics and delivery efficiency compared to conventional processes.

ROS Feature
Zelex SLE series sex doll heads are made from soft silicone, offering excellent softness and durability.

This series features a movable jaw structure and ROS functionality. The oral cavity uses a modular system design, allowing the teeth components to be easily removed and reinstalled to meet users’ diverse needs.

Hair Implantation
Zelex SLE series now offers ten specially designed sex doll heads optimized for hair implantation.

Zelex SLE series uses an innovative three-layer scalp structure technology. Combined with advanced hair implantation techniques, this structure significantly improves hair durability and creates a natural, seamless hairline. This effectively solves the hair loss issue caused by the realistic oral features in traditional soft silicone heads.
Due to the precise and detailed handmade process, the production cycle for each product ranges from 15 to 20 days.

Note
- The doll heads attach to the body using an M8 to M16 screw connection. Specifically, the head connector uses M8-type screws, while the body connector uses M16-type screws. Additionally, the doll head and screws are welded together and cannot be detached.
- Production time on individual heads is 5 – 7 working days for non-hair implanted heads and 9 – 11 working days for heads with hair implants.
- There may be slight differences in style and color between the promotional images of the doll head and the factory images.
- Coeros also offers extra sets of eyes and wigs to choose from to give your sex doll different styles and colors.
- Additionally, Coeros also offers many elegant and simple doll head stands to help you better display and store your doll heads.
