164cm E-Cup Realistic Silicone Sex Doll-Irontech Doll-[Special Offer]

Real Oral Structure(ROS) head is an upgraded soft-head structure with a movable jaw, teeth, and tongue. It gives the head a more complete internal design than a standard soft head. For selected head sculpts, ROS Max adds extra support around the lower eyelids, helping the face keep a more natural shape when the mouth is opened.

ROS-compatible heads include: S1, S17, S18, S20, S26, S29, S37, S40, T3, T4, and T5.

ROS Max compatible heads include: S10, S13, S14, S19, S20, S27, S30, S31, S32, S33, S40, T1, T3, T4, A3, A4, A5, A6, B1, and B2.

Irontech offers regular and ultra soft body options.

Ultra Soft Body offers a softer and more flexible feel, especially in areas like the belly and thighs, creating a more natural touch compared to the regular option.

However, softer materials require more careful handling. Ultra Soft is less resistant to wear over time, so it’s better suited for users who are willing to take extra care during use and maintenance.

If durability and easier maintenance are your priority, regular softness provides a firmer structure and holds up better over time.

Irontech also offers targeted softness upgrades for specific areas, allowing you to enhance certain parts without changing the entire body feel.

Irontech pays close attention to both facial makeup and body painting, so the doll feels more complete from head to toe. The face is designed around each head sculpt’s own style, with balanced skin tones, clear eyebrows, lip color, eye details, and a stronger sense of personality. The body painting focuses on subtle color transitions instead of a flat single-tone finish, with added detail around areas such as the areola, joints, hands, feet, neck, and body contours.

Irontech’s standard articulated fingers use a joint-based structure instead of simple wire fingers, giving the hands better control and more natural posing. The upgraded ball-jointed hand skeleton adds a wider wrist movement range, rounded fingertips to reduce internal puncture risk, a stronger internal structure, and better bonding with silicone to reduce shifting.

Irontech offers optional robotic movement for selected models.

Auto Blowjob moves the head up and down with a built-in motor to simulate oral motion. The speed is usually adjustable.

Electric Hip & Waist adds powered movement to the waist and hips, creating rotating or swinging motion.Some body types can support both features together, but not every size or version is compatible.

The control unit stays outside the body. It is easier to replace, maintain, or repair.

The device is built inside the body. It looks cleaner, but it is harder to repair.This feature works through different rhythm settings, creating continuous feedback instead of one simple motion.

Auto Suck Mouth creates a repeated suction-like feeling inside the mouth, adding automatic feedback during oral interaction. It is different from Auto Blowjob.

Auto Suck Mouth focuses on internal mouth suction and rhythm changes.

Auto Blowjob focuses on automatic head or upper-body movement.This feature is mainly designed for ROS and ROS Max heads, so not every head sculpt can support it.For a more complete experience, it is recommended to pair it with oral heating.

Body Heating is an optional feature that helps warm the doll closer to body temperature for a more natural feel.

Based on our own testing, when the room temperature is around 25°C / 77°F, it takes about 80 minutes for a silicone doll to warm up to around 35°C / 95°F.

Heating time may vary depending on room temperature and doll size.

The Moaning Function uses built-in touch sensors to trigger pre-recorded moaning sounds.

There are five touch-sensitive points on the body. When these areas are touched, the doll can respond with sound feedback, creating a more interactive experience.

This is a pre-recorded audio function, so it does not generate live conversation or AI-based voice responses.
