Specifications Sex Doll FAQs
Understanding the technical engineering behind a high-end lifelike companion is essential for selecting a partner that aligns with your aesthetic and tactile preferences. At HKSexDoll, our specifications are defined by medical-grade material integrity and advanced kinetic engineering. This technical FAQ hub provides a deep dive into the material science, skeletal articulation, and precise anthropometric measurements that distinguish our collection from mass-market alternatives.
Our goal is to provide seasoned collectors and first-time buyers with the data required to make an informed investment, ensuring your chosen companion meets the highest standards of realism, weight distribution, and structural durability.
Advanced Material Science: Medical-Grade TPE & Silicone
The tactile experience of an HKSexDoll is governed by the purity of our polymers. We utilize platinum-cured medical-grade silicone and high-density thermoplastic elastomers (TPE). Our silicone models offer a firmer, “muscle-like” density with hyper-realistic skin textures (including visible pores and capillaries), while our TPE models are celebrated for their “soft-tissue” realism and natural body-fat elasticity. Every material batch is SGS certified for skin safety, ensuring they are non-porous, hypoallergenic, and free from harmful phthalates or volatile organic compounds (VOCs).
The EVO Skeleton: Articulated Stainless Steel Engineering
Beneath the soft exterior lies the EVO-Skeleton system — a precision-engineered stainless steel frame featuring multi-axis articulated joints. Unlike standard skeletons, our EVO frames utilize reinforced ball-bearings in the hips and shoulders, allowing for over 45 points of articulation that mimic human range of motion. This internal architecture is designed to support the doll’s “billing weight” while maintaining pose stability for photography or display, ensuring that joint tension remains consistent even after years of use.
Anthropometric Precision & Custom Measurements
Realism is a matter of millimeters. Our specifications cover exhaustive physical data points, including shoulder width, vaginal depth, and palm length. Each model, from our 100cm torsos to our 171cm full-size masterpieces, undergoes a rigorous calibration process. We provide detailed anthropometric charts to help you visualize the physical presence of your companion in your space. This level of data transparency ensures that when you choose a specific height or cup size, the physical reality matches the technical datasheet perfectly.
At HKSexDoll, we don’t just sell dolls; we provide engineered art pieces. By mastering the balance between anatomical accuracy and structural integrity, we deliver the world’s most sophisticated companions.

How much does a flat chest sex doll weigh?
In this collection, a 140cm TPE flat chest doll weighs about 23kg and a 158cm model about 28kg. Expect the shipped carton to weigh more; see our weight by height guide.
Is a flat chest sex doll completely flat?
No. In the doll industry, “flat chest” means the smallest cup sizes, usually AA to B. The bust is small but still has a natural shape. In this collection, bust measurements run from 66cm to 75cm; check each product page for the exact cup and measurements.
What’s the lightest E-cup doll?
The E-cup silicone torso (80cm, chest and hips only) is by far the lightest and easiest to store. Among full-body options, the petite 150cm frame is the most manageable weight.
How big is an E-cup on a sex doll?
Large and clearly full, but how dramatic it looks depends entirely on the body. On a petite 150cm frame an E-cup is top-heavy and eye-catching; on a 168cm doll the same cup reads as a natural large bust. Choose the frame, not just the cup number.
Which black dolls are in US or EU stock?
Most of this collection ships from US stock, with one model (Full Black Hair 156cm D-Cup) in EU stock. In-stock items ship within days, not the usual made-to-order wait.
Can Japanese dolls be posed naturally?
Yes. Every model has an internal articulated stainless-steel skeleton with jointed neck, shoulders, elbows, hips and knees, supporting standing, seated and relaxed positions.
Are 165cm dolls heavy to move?
It depends entirely on the build. Lightweight and anime-styled models are the easiest to handle, while flagship full-silicone H-cup models weigh noticeably more. Pick by build, not just height.
How tall is a 165cm sex doll in feet?
165cm is 5ft 5in — average adult-woman height, which is why the range reads as fully life-size rather than compact.
Are 168cm dolls all BBW or curvy?
The tier leans strongly toward wide-hip and voluptuous builds — including measured curves like Kim (104cm hips) and full-figure BBW models like Luna — but it isn’t exclusively plus-size. If body type matters more than height, browse the dedicated BBW range.
How tall is a 168cm sex doll in feet?
168cm is 5ft 6in — tall enough to carry full, curvy proportions naturally, with real statuesque presence.
Can I realistically hide a sex doll?
A full-size doll is a person-sized storage problem — plan the hiding spot before you buy. A torso or a smaller doll fits in a box, drawer, or case and solves the discretion issue almost entirely.
How much do petite 148–158cm dolls weigh, and are they easy to store?
Depending on material and body type, they typically weigh 15–30kg. Silicone runs heavier than TPE at the same height. Plan for storage and handling before buying — many owners keep them in a padded case or dedicated closet and use a hanging kit to protect the skin.
Can I customize eye color, hair, and functional add-ons?
Yes, you can fully personalize eye colors, wig styles, skin tones, standing feet, movable jaw functions, and gel breast options directly on each product page.
How much does a 158cm (5’2″) sex doll weigh?
Most 158cm life size dolls weigh between 28kg and 38kg (61–83 lbs), depending on bust size and skeleton type. This makes a 5ft2 doll significantly easier to move, dress, and store compared to taller 165cm+ models.
How heavy are BBW sex dolls?
Heavier than slim dolls of the same height — all the curves are extra material. The exact weight is on each product’s page. If lifting is a concern, look for weight-reduced silicone builds or a BBW torso. Quick self-test: if you can carry a 40 kg suitcase upstairs, most standard builds are fine.
How long does a C cup sex doll last?
A well-maintained C cup sex doll can last 3–5 years or longer. TPE models offer a softer feel but require regular care, while silicone models tend to last longer with easier maintenance. Proper cleaning, storage, and handling play a key role in maximizing lifespan.
