Each 12" doll is made of durable, lightweight vinyl with 21 points of articulation including double jointing at the knees and elbows. This doll is not a strung BJD but rather a mechanically multi-jointed doll. You won't believe the poseability!! Wigged (not rooted) hair and inset eyes. Artfully designed by Ruby Ho. Senson dolls are hard vinyl. Lia dolls are vinyl and hard plastic.
