1. Skin color
Silicone dolls currently provide 4 skin colors to choose from, namely natural, tanned, dark tanned, and black. You can choose and customize according to your preferences, or if you like the skin color of our product pictures, you can choose "same as picture" so that you can make a quick decision.
Note: Due to the different color effects of shooting lights and pictures on different devices, there will be slight differences between the actual product and the photo, but we will take pictures or videos of the actual product for you to confirm before shipping. So please check your email to avoid missing messages because the email is identified as spam.
2. Head material
There are usually two or three options in this part, including hard silicone head, soft silicone head and ROS head. If there are only two options, hard silicone head and soft silicone head, it means that this head type does not support movable chin. However, don't worry about making the wrong choice. If there is a conflict in the options, we will contact you by email for negotiation.
2.1. Comparison of hard silicone head and soft silicone head
It can be seen from the video that hard silicone head and soft silicone head have differences in function and softness.
Hard silicone head: Relatively speaking, it feels harder and does not have oral passage and movable chin functions. However, hard silicone head can choose hair transplantation, eyebrow transplantation and eyelash transplantation, which is not available in soft silicone head.
Soft silicone head: This material feels softer and has better ductility, so it has an oral passage. However, this type of head can only wear wigs, and cannot be transplanted with eyebrows and eyelashes. Usually the default is thrush.
The two materials have their own advantages and disadvantages in terms of function and softness. The choice of material will affect other options, so this needs to be considered carefully before placing an order.
2.2. ROS function and structure display
As mentioned above, there is also a ROS head, also called a movable chin head type. Compared with the soft silicone head, it only has a simple channel, and its internal structure is more complex and delicate. For example, silicone teeth and tongue are usually configured inside, so that you can have a more realistic experience when you use it for oral sex. The following is a video of the function display:
2.3. ROS head heating function
Considering the low temperature in autumn and winter, in order to improve the user's experience in low temperature environments, an oral heating function can also be selected here. After powering on, wait for 25-30 minutes to reach the appropriate temperature. This function is humanized and takes into account the use conditions in different seasons, which is very practical.
2.4. ROS head auto-sucking function
When you select this feature, an external drive is provided. It needs to be connected to the jack behind the doll's ear. Once connected, press and hold the power button to turn it on. Click to switch between different languages—English/Japanese/Korean/Chinese/Off. Pressing the M button activates the automatic clamping function. The moderate clamping force and friction particles on the inner wall of the channel will greatly satisfy you.
3. Head type options
The brand silicone head currently has 36 female head options and 8 male head options. You can buy according to your preferences or official matching pictures.
The heads that support ROS are: S1, S17, S18, S20, S26, S29, S37, S40, and the new T series: T3, T4, and T5. More new heads are coming soon. Below is a list of all the heads.
4. Sway-Pivot Adaptor & Head Stand
4.1. Sway-Pivot Adaptor
The brand has made a major upgrade in the head installation method.
Quick Plug-in: The head can only be slightly shaken after installation.
Movable Quick Plug-in: After installation, it can be shaken 360° in a large range, and can be matched with the body to pose in various postures.
4.2. Head Stand
If you have multiple heads or need to store the body and head separately, this bracket is a good choice. At the same time, you can use it as a display bracket so that you can match your doll with different wigs or hair accessories. Below is the video of the instructions for using the bracket:
5. Facial makeup and body makeup
The brand has recently completed the upgrade and option adjustment, and the original S+ facial makeup and S+ body makeup worth $298 are given away for free. Compared with regular makeup, S+ makeup makes fine decorations on various parts of the body, making the sex doll closer to real people.
Below is a comparison of various parts of regular makeup and S+ makeup:
Note: The details of S+ makeup have a more obvious contrast on natural skin color, and the contrast may not be obvious on dark skin.
For facial makeup, we support customized makeup and freckles. If you have any customized needs, you can contact us for customization.
6. Wigs and hair transplants
The brand provides 18 European and American styles and 12 Asian styles of wigs. The following are the corresponding wig option photos:
Hair transplants are available in 3 colors. The following are the corresponding hair transplant option photos:
At the same time, we provide dreadlock wig options.
7. Eye Color
There are 26 options for the eyeballs, and the following are photos of the options for the eyeballs:
8. Finger Skeleton
There are currently two mainstream types of finger bones, one is the wire-type finger bones, and the other is the ball-jointed finger bones. The first is the default configuration of most brands. Due to the characteristics of the wire, this type of palm usually rebounds quickly after kneading, and there is no way to flexibly adjust the posture. At the same time, its front end may cause the wire to pierce the palm due to the strong kneading force. The ball-jointed finger bones are upgraded options based on these two user feedback. The multi-section finger bones with ball joints can not only make the doll's fingers bend as flexibly as real people, but also greatly reduce the probability of palm piercing. Below is a demonstration video of different finger bones:
9. Fingernails and toenails
Fingernails and toenails are currently available in a variety of colors, as shown below:
10. Breasts Option
10.1 Areola color
In the color part, we have upgraded the makeup process, greatly improving the degree of reality, and a variety of colors are also available for you to choose from. Below are the option photos corresponding to the areola color:
10.2 Areola size
We have three options by default: 3cm, 4cm, and 5cm. If you want to choose a larger size, you can tell us for customization.
10.3 Gel Breast vs Softer Gel Breast
The brand defaults to Gel Breasts, which can be upgraded to Softer Gel Breast. The upgraded version feels better and softer. Below is a comparison video.
11. Softer thigh and abdomen
The softening upgrade of the thigh and abdomen can allow you to get more sensitive feedback when your body collides or kneads the sex doll during sexual intercourse, improving your sexual intercourse experience. The following is a demonstration video of the doll after softening:
12. Vagina
12.1 Vagina color
The color of the vulva is the same as the color of the areola. Through the upgrade of the process, it can provide more realistic makeup and enhance the visual experience. Below are the photos of the options for the genital color:
12.2 Vaginal Texture
The genital texture is currently only applicable to the one-piece vagina. There are many options for vaginal texture. Different vaginal textures have different textures designed on the inner wall, and some of them can increase stimulation and enhance the sexual experience through curved internal structures. Below are the photos of the options for the genital texture:
12.3 Automatic clamping and suction vagina
Compared with the conventional model, this vagina can simulate the action and strength of real people's clamping and suction, allowing you to free your hands and enjoy the sexual intercourse process. And it is controlled by external drive, which is very safe and can be washed. Below is the demonstration video:
13. Feet Option
For dolls of different materials, the treatment of feet will be different. The body of TPE material can only choose not to stand or stand with nails, while the body of silicone material can choose to stand without nails (hard feet) or not stand. At present, the standing function is a free default option, and you can choose according to your needs. The following is a demonstration video of the hard feet of silicone dolls:
14. Body Skeleton
As the core part of the sex doll, the choice of skeleton is very important. It is one of the decisive factors for the service life of the doll. We can see on social media platforms that some users have purchased dolls with broken spines. This is the conventional skeleton used, and this loss is irreparable.
The brand defaults to the EVO MAX skeleton, which has super high structural strength. As can be seen from the video below, it can withstand the violent impact of adults, and the high-strength stainless steel pipe can withstand 3 seconds under the high-speed cutting machine without being damaged. Moreover, we have many years of production experience in adjusting the tightness of the joints, while ensuring the service life, giving users more flexible adjustment angles. The following is the EVO MAX skeleton demonstration video:

The free accessories package includes an instruction manual, a heating rod, a drying rod, underwear, a comb and a manual cleaning pump. We recommend that you read the instructions in detail after receiving the goods. Following the above suggestions can greatly increase the service life of the doll.
