Sara and Zoe
Sara and Zoe time-share one body, made of thermoplastic (TPE) by YLDoll in China in 2014. Such dolls are less expensive than silicone rubber dolls, but they are more fragile, much harder to clean (they collect dust and dirt and you cannot get it off) and even heavier.
Zoe is a different head who time-shares Sara’s body. Lucy is a silicone rubber doll.
