I believe SE doll TPE dolls are produced in the Jinsan group of factories. I am not sure if Jinsan produce Silicone dolls themselves in their own factory or it belongs to Piperdoll, there are a lot of theories to where Angel Kiss dolls are made. A few years back an exclusive WM vendor posted a video on UKLDF of the latest Angel Kiss model, the video was quickly removed by the vendor, many members had already commented on the Piper dolls hanging in the background. I have asked who makes SE silicone dolls many times, have never had a proper answer, 'it's not made by them' and 'they are made in their own factory' are not valid answers. I have the SE doll 160 Silicone pro and a SMDoll 160cm Silicone doll, put a blindfold on and to feel them they are the same doll, other than a slight difference in their body sculpt they are so very similar, the SM dolls feet have the same extra useless, unnecessary, stupid, pivoting extra joint that the piper dolls have, I am convinced they are all made at the same factory, but I am told frequently I am wrong...
Anyhow, If the doll you are looking at getting is anything like SE doll 160 silicone pro, here are a few good and bad bits. she looks amazing, the SE pro silicone is awesome to feel, She's got one of the softest pair of doll breasts I have on any doll, but the softness is only skin deep, the silicone is a soft thin cushion before hitting a lightweight rock hard foam core and she feels like a brick. Her arm joints came loose within a month without really moving her much.... I guess that will not be a concern on the model you are looking at.. If I can remember correctly her left hip is loose too, to me they are just an average doll manufacturer. If I was looking to buy a full doll, I wouldn't look at a SE doll, I think there are better made dolls available for similar price.... but there are a lot worse also.
