The following section provides a detailed overview of the advanced features available on Funwest silicone sex dolls.

1. ROS & Movable Jaw

The Funwest silicone doll collection currently offers 20 different head sculpts and 47 makeup options, giving shoppers plenty of flexibility when choosing their preferred appearance. The head sculpts are divided into three categories: non-ROS silicone heads, silicone heads that can be upgraded to ROS, and silicone heads that come with ROS as standard.

Silicone Head Without ROS

The silicone head sculpts listed below are not currently available with ROS functionality and cannot be upgraded to ROS. They are available in either firm silicone or soft silicone. The soft silicone versions feature an open oral cavity with an internal depth of approximately 13 cm (5.1 inches) and are designed for oral use.

2. Realistic Skin Texture

For shoppers who prioritize a highly realistic appearance, the 157G, 159A, and 159F bodies in the FS Series are available with an optional realistic skin texture upgrade.

With this upgrade, the doll’s skin features more clearly defined and detailed textures designed to replicate the appearance of real human skin. Areas such as the breasts, vulva, knees, hands, and feet receive additional texturing for greater surface detail, creating an overall appearance that more closely resembles natural human skin.

Watch the manufacturer’s video below for a closer look at the details and realistic appearance of the FS Series skin texture.

3. Movable Eyelids

Movable eyelids feature articulated structures in both the upper and lower eyelids, allowing the eye-opening position to be manually adjusted. This option is available for ROS heads and soft silicone heads, allowing you to create different eye positions, including open, closed, and partially closed eyes.

When combined with a movable jaw, the eyelids and jaw can be adjusted together to create a wider range of natural-looking facial expressions, giving the doll a more lifelike and expressive appearance.

4. Gel-filled Breasts

Funwest FS Series dolls come standard with gel-filled breasts. Compared with conventional filling materials, gel filling provides a softer, more natural feel, offering a tactile experience that more closely resembles the softness of the human body when touched or gently pressed.

Watch the video below to see the softness and feel of the gel-filled breasts on Funwest FS Series dolls.

5. Wired Toes & Articulated Toes

Wired Toes

Wired Toe

Wired toes are a standard feature on Funwest silicone dolls. This feature allows the toes to move naturally, enhancing the doll’s flexibility and overall realism.

Articulated Toes

Articulated Toes feature a joint structure designed to more closely replicate the natural movement of human toes, with additional points of articulation for greater flexibility and more precise positioning. This is an advanced option for shoppers who value enhanced detail and poseability, and it can be selected according to individual preferences.

6. Auto-Blowjob & Electric Hips

Auto-blowjob Function

Funwest silicone dolls with the automatic oral function require an external power supply. The adapter controls the operating frequency by adjusting the output voltage—the higher the voltage, the faster the movement frequency. For first-time use, we recommend starting at a lower setting and gradually increasing the frequency until you find a comfortable pace.

The mechanical unit is mounted to the doll’s metal frame at the waist and is compatible with the electric hips function, allowing both features to be configured together.

Electric Hips

Funwest’s electric hip function requires an external power supply, with the available functions powered through the included adapter. The hip movement speed can be controlled by adjusting the adapter’s output voltage—the higher the voltage, the faster the movement.

The mechanical unit is mounted to the doll’s metal frame at the waist and is compatible with the automatic oral function, allowing both features to be configured together.

Auto-Blowjob & Electric Hips Integrated System

The Auto-Blowjob and Electric Hips functions can be integrated into a single system powered and controlled through an external power supply. Each function has its own independent switch, while the operating frequency can be adjusted by changing the adapter’s output voltage.

The two functions can be operated simultaneously or used independently, allowing users to choose the configuration that best suits their preferences.

7. Soft Cheeks

Soft Cheeks is an optional upgrade that uses soft silicone material on both sides of the doll’s cheeks, creating a softer, more compressible feel for a tactile experience when gently squeezing or massaging the cheeks. This feature is available as a paid upgrade and can currently be added only to ROS heads.

8. Oral Heating (Soft Head)

All soft silicone heads are compatible with the optional oral heating function. Please note that ROS silicone heads and the oral heating function cannot be configured together, as these two options are mutually exclusive.

9. Auto-suckin Vagina

To accommodate different preferences, FS Series dolls can be upgraded with an **external automatic system**. The device allows users to adjust the operating rhythm according to their preferences and features a built-in voice function for a more interactive and convenient experience.

After upgrading to the **Auto-Sucking Vagina** function, the doll does not have an anal opening and therefore does not support anal use.

Watch the video below to get a closer look at the Auto-Sucking Vagina function and how it works.
