All the OS/OSP/OSP PRO has the same skin long lasting pigmenting, and all of them are by default configured with OS head. If we rank by the softness, yes. OSP PLUS>OSP>OS. But for most new XYcolo buyers, the OSP is good enough.
Correspondingly, all the PS/PSP/PSP PLUS has the same body make up. By default the PSP/ PSP PLUS configured with a OS head, the PS body by default with a PS head. The PS whole doll is an entry level of XYcolo silcione doll, it has a price level of TPE. With a TPE doll price, you can have a pure SGS verified silicone doll!
