Before 2009, Jin San was just a little-known costume model props factory in Zhongshan, Guangdong. Under the leadership of some companies in the industry, Jinsan started its TPE physical doll OEM business in 2010. With the take-off of China's physical doll industry, Jinsan has developed into the largest TPE doll manufacturer in China, second only to ExDoll in domestic popularity, and also explores overseas markets and exports and sells under the "WM Doll" brand.
 
Jinsan is higher than ExDoll in terms of sales, this is because the TPE material it uses has greatly reduced the price of the product, and the highest price model is only more than 10,000 yuan, which is much closer to the people than the silicone doll with a price of tens of thousands, and has become the entry choice of many baby friends. In addition, Kingsoft's dolls cover a height of 65cm to 168cm, and there is basically a choice every few centimeters, which can adapt to the needs of more users. However, in terms of makeup, hair, and face shape, there is still a clear gap between Jin San and ExDoll. For example, in terms of eyelashes, Kim Sanduo uses false eyelashes, and there are fewer customization options, which cannot be compared with the top manufacturers in terms of look and feel. In response to this situation, some users will separately buy the head sculpture of Simu and ExDoll to install on Jinsan's body, which is a compromise solution.
 
Jinsan's physical doll uses TPE as the skin material, although the cost is lower than that of silicone, but it also has the advantage that silicone is not comparable. Taking the touch of the chest as an example, Jin San uses hollow TPE on the chest of the small body doll, which feels softer than the full silicone, and the shaking feeling of the chest is closer to the real situation when swinging the body from side to side. The disadvantage of TPE is that the taste will be larger than that of silicone, and it is easier to dye than silicone, and there will be irreversible deformation after a long time. That's why TPE doll manufacturers like Jinsan aren't willing to put the effort into delving into the details.
 
On the official channel, Jin San divides his dolls into series such as "Mature Royal Sister", "Two-dimensional Cute Girl", "Tall Model", "Wife and Young Wife", but in fact, there is no obvious technological distinction between the series. All collections share the same body, but the head sculpture of the corresponding style is fitted to it. No. 85 head sculpture is a popular among Jinsan, with the most balanced facial features, which can control different styles of makeup and dressing, and 168cm is the most popular height size, priced at 6980 yuan. However, although the 168cm doll has a slender body, it weighs 40kg, so it is only recommended for users who are more confident in their strength.
 
In recent years, Kim San has added heating and vocalization functions to the doll. After 30 minutes of plugging in the power supply, the surface of the skin will feel hot, and about 50 minutes it will be close to the human body temperature; The sound module is MP3 plus speaker, the content is blunt, and the interactivity is not strong, but it can indeed meet the needs of some users. In addition, the skeleton of the golden third does not have a loose joint design, which is more laborious than ExDoll when moving and posing.
 
Jin San sells different head sculptures at home and abroad. For the European and American markets, the skin color and facial features of European and American aesthetics have been specially launched, and the pricing is also higher than that of the domestic market. The same 165cm doll is sold for $2,600 abroad, while it is only about $9,000 in China.
