Here are some words you might run into and their meanings!

-- BJD: the acronym for ball-jointed doll. Blythe is not a ball-jointed doll, nor is the PureNeemo body, but sometimes people will use the term anyway to get more hits on their listings for doll items.

-- boggled eyes: "boggled" is a term used to describe the lack of eyelid showing on a Blythe doll when she has her eyes open. The original 6 Takara BL releases (Parco, Mondrian, Hollywood, Rosie Red, All Gold in One, and Kozy Kape) all came boggled in their initial factory release. After Kozy Kape, Takara changed the eyelid design to be slightly visible with the eyes open. "Boggling" may also refer to the customization process where one removes a small plastic section usually only a few milimeters thick of the eye mechanism in order to achieve a boggled look.

-- face mold: when they shape the plastic to become Blythe's lovely face, they use a mold. They have used quite a few over the years; they all look quite similar, but you may start to notice subtle differences when you look closely. The face molds in chronological order are: the original Kenner mold, BL, EBL (excellence), SBL (superior), RBL (radiance), FBL (fairest), RBL+ (radiance+), ADG (Ashton Drake Galleries), Radiance Renew, and Radiance Evolution.

-- face-up: this is the process of customizing a face-plate on a doll. It involves sanding off the original makeup and creating a base that pigment can adhere to, then painting on a new face. The faces are then protected with a spray-on sealant.

-- Junie Moon: The store that officially sells Blythe; they are owned by CWC. There are three locations in Tokyo: Daikanyama, Shinjuku, and Harajuku, as well as a location in Horie, Osaka. They have an online shop and ship internationally.

-- stock: A stock doll is an official doll. People use this term to refer to dolls that haven't been customized at all. It can also refer to the clothes that come with official releases.

-- TaoBao Blythe (TBL): This is a term for fake Blythe dolls, named after the shopping website where many fake Blythe dolls are sold. They are typically listed as factory or nude Blythe dolls, and may come on PureNeemo or fake Takara bodies. They typically have hair color and eye color combinations inconsistent with official releases, but there are some fake Blythes that mimic the stock clothing and the box.
