Sanhui doll skeleton: joints and poses

Flexi Edition (EVO): what is inside

Every full-size Sanhui doll is built for posing. Sanhui describes the frame as a fully poseable stainless steel skeleton cushioned in soft foam. Since September 2019 it has been the Flexi Edition, which Sanhui says moves more smoothly, through a wider range, and lasts longer than the earlier design. It now comes standard at no extra cost, and the order form lists it as EVO.

The listings describe ball joints, and you choose the joint tension: standard or loose. Sanhui notes that loose joints move with less effort but may not hold some positions, so standard tension suits posing. New joints can feel tight at first; Sanhui’s guide calls that normal and says they ease with use.

Standard bodies attach the head with a plug-in neck joint, while AIO models have a seamless neck. How that changes your choice of face is covered in the guide to Sanhui doll faces.

Shoulders, fingers, hands and feet

• Shrugging shoulders

  Added to the Flexi skeleton in April 2022 at no extra cost, so the shoulders lift for more natural poses.

• Articulated fingers

  +$130 since March 2022. The fingers bend, so the hands hold a pose for photos.

• Hard hands

  +$130 since November 2024. One owner reports no finger punctures after a year with hard hands and feet.

• Hard feet

  +$100. Sanhui says they look neater, with no exposed studs, and let the doll stand for short periods. Their color differs visibly from the body.

Standard feet come either without standing support or with standing studs, both at no extra cost. Soft hands and feet show wear first: the soft hands of one four-year-old doll looked badly worn, which makes the hard options worth a look if you handle the doll every day. One owner adds that a doll on hard feet needs shoes and balances less easily than on a metal stand.

Pose limits Sanhui sets

Sanhui’s pose rules protect both the skeleton and your warranty. Its user guide sets them out, and a May 2016 notice, issued after two owners’ dolls broke at the wrist, repeats the main one: avoid moves beyond a real person’s range, such as a forced sideways bend of the wrist.

1. 01

   Stay inside the range

   Don’t force unusual poses or bend any joint against its natural direction.

2. 02

   Reset between poses

   Return the doll to a neutral position before setting the next pose, as Sanhui advises.

3. 03

   Stand briefly, feet flat

   Stand the doll only for short periods, on a flat, soft surface, with both feet fully down; leaning it against a support is better. Otherwise the feet get damaged or the frame can push through the silicone.

4. 04

   Keep weight off the chest

   Don’t leave the doll face down with its weight on the chest, and don’t press down on it hard.

5. 05

   Store in a relaxed pose

   Long hours bent at a joint crease the silicone and can eventually tear it.

Some limits are mechanical. A 2026 owner of a 168 cm doll reports that the thighs fold almost to the chest, while the knees stop short of closing fully: the heels can’t reach the back of the thighs.

What loosens Sanhui joints: owner reports

Owner reports run both ways, from years without trouble to joints loosening over one to two years of use and a few skeleton breaks. Each row below is an individual case with its year.

Sanhui’s own guidance names the habits to avoid: forcing joints past their range and leaving the doll standing for long. Its 2019 policy excluded damage from joints pushed beyond their range, so keeping to the pose limits keeps the warranty described in the Sanhui doll review on your side.

Weight from 28 to 53 kg: what it means

A steel frame plus silicone gives a Sanhui doll real weight. Listed weights run from 28 to 38 kg for standard bodies and up to 53 kg for the tallest AIO. Sanhui offers no lighter version, and each optional soft zone adds about 0.3 kg, according to Sanhui.

Weight decides daily handling: every lift for dressing, bathing or posing moves that mass. If you will handle the doll alone, the 150 and 156 cm bodies and the 160 cm AIO are the lightest in the lineup. Plan for two people with the 52–53 kg models, which ship in a box of about 175 × 47 × 31 cm. Read the listing as a guide: one owner reported a 168 cm doll at about 36 kg against 33 kg listed. All sizes are compared on the Sanhui doll guide home page.

Care and repair

1. 01

   Smooth creases early

   Platinum silicone has some memory. Rub a crease from a bend back and forth soon; Sanhui warns that a crease left too long is hard to recover.

2. 02

   Wash, dry, powder

   Wash under a shower without soaking, dry the doll, then powder the skin. Silicone oil rising to the surface is normal, Sanhui says.

3. 03

   Store it right

   Keep the doll at 5–35 °C (41–95 °F), out of direct sun, off dyed fabric and leather, with nothing heavy on top and no tight clothes.

4. 04

   Hang it with the right bolt

   The neck thread is recessed, so hanging needs a special eye bolt; owners say Sanhui sells it separately.

5. 05

   Fix tears at once

   Stop using the doll, glue the tear with Sanhui’s repair adhesive and let it cure for 24 hours. Sanhui notes that a seam will stay visible.

For repairs under warranty, start with whoever sold you the doll: Sanhui for direct orders, the store for store orders. The Sanhui doll official site guide explains how each route works.
