problem was corrected with later releases. Another common problem with the Type 1 body is vertical splitting between the two halves of the legs. All Pullips released on the Type 1 body have rooted hair. Starting in January 2004 with the release of Pullip Venus, a new stock body was introduced. The Type 2 body had a soft torso, no visible screws, and joints that could be pulled apart. This body had more realistic proportions and, to date, is the most posable, flexible, and articulated Pullip stock body ever released. The primary disadvantage of this body is that the soft plastic torso causes chemical melt on the hard plastic limbs and pieces that remain in contact with it, including the hip joint/lower torso piece and the ball joints of the shoulders. If measures are not actively taken to prevent it, the soft torso can also cause a ring of chemical melt around the neck hole in Pullip's head. Although chemical melt is the most widely recognized problem with the Type 2 body, it is not known whether environmental conditions (heat, humidity) exacerbate the melt. Other common problems with the Type 2 body are that limbs can fall off or pull apart too easily and that the soft torso can pop out of the hip joint. Only the first three Pullips released on a Type 2 body (Venus, Savon, and Nomado) have rooted hair; all subsequent releases, starting with Arietta in March 2004, have glued-on wigs, which can be removed and changed if desired. With the dual release of Lan Ake and Lan Ai in August 2005, the next stock body, the Type 3, was introduced. Relative to the Type 2 body, the Type 3 had less articulation; a smaller, more juvenile sculpt; and hinged wrist and ankle joints. While sturdier than its predecessors, the Type 3 was the least posable stock body and remains so even today. Many Pullip collectors expressed displeasure with the Type 3 body, especially after having grown accustomed to the superior aesthetics and possibility of the Type 2. The most common problem with the Type 3 body is wrist cracking, which was prevalent with the Pullips released after January 2007, starting with Stica. Additionally, the leg and knee joints on the Type 3 body often make a creaking noise when bent. In January 2009 with the release of Neo Noir, another Pullip stock body was introduced:
