What is a BJD?
A ball-jointed doll (BJD) is a fully posable collectible doll cast in resin, held together by elastic cord and designed to be customized from face to toe.
Definition
BJD stands for ball-jointed doll. Every major joint - neck, shoulders, elbows, wrists, hips, knees and ankles - is a ball-and-socket joint, so the doll can sit, stand and hold natural poses. Most BJDs are cast in polyurethane resin, which feels weighty and smooth, almost like porcelain.
Anatomy of a BJD
- Parts: typically composed of 7 or more parts, including the head, torso, arms and legs.
- Stringing: thick elastic cord runs through the body and pulls the parts together; the tension keeps poses stable.
- S-Hook: a metal S-shaped hook attached to the ends of the elastic cord or joint connections to secure the head, neck, wrists and ankles.
- Joints: ball joints, and on many dolls double joints at the elbows and knees for a deeper bend.
- Head: usually hollow with a removable head cap so the eyes can be changed; eyes are held with putty or a magnet.
Made to be customized
- Face-up: hand-painted makeup with pastels and acrylics, sealed with matte varnish.
- Eyes: swappable eyes in glass, urethane or resin, sized in millimetres.
- Wigs: sized by head circumference in inches, in synthetic fibre or mohair.
- Outfits & shoes: made for each size, from everyday clothes to elaborate costumes.
Why BJDs are loved
A BJD is a blank canvas: two owners of the same doll can end up with completely different characters. Collectors enjoy photography, sewing, painting, storytelling and meeting other fans, and a well-cared-for resin doll can last for decades.
DOLLSN Skin Tone Standard: White Skin vs. Normal Skin
DOLLSN ball-jointed dolls are cast in two primary standard resin tones: White Skin (Milk-White) and Normal Skin. Because every BJD company mixes resin pigments differently, checking DOLLSN's official head-cap colour comparison helps when choosing a doll or planning a cross-brand hybrid.
- White Skin (WS · Left in photo): A pure, milky porcelain white tone without yellow cast. Used as the standard skin on DOLLSN's 26cm (1/6 USD) dolls and selected releases, ideal for bright pastel face-ups and ethereal concepts.
- Normal Skin (NS · Right in photo): A warm, natural apricot-peach beige tone with a healthy complexion. Used across DOLLSN's 42-48cm (1/4 MSD) dolls and main lineup, photographing naturally in both indoor and outdoor lighting.
- Hybrid & Colour-Matching Tip: Even when two makers use the names "Normal" or "White", undertones vary. Use the side-by-side comparison photo above as DOLLSN's reference, and blend minor tone differences with face-up shading or neck blushing.
