Recommended models: Zhongchuan 001, Zhongchuan 002
 
The technical requirements for the production of polyurethane condoms are relatively high, and only a few condom manufacturers in Japan have production capacity in the world. At the beginning of 2018, the polyurethane condom production line established by Zhongchuan in Lanzhou began to be put into operation one after another, and the planned annual output of 10 production lines in the entire base will reach 1 billion, becoming the world's largest waterborne polyurethane condom production base.
 
Although polyurethane condoms are not mainstream in the market, they are products at the top of the pyramid. Zhongchuan is currently the only Chinese brand that can produce polyurethane condoms, and the elephant 001 polyurethane condom is produced by Zhongchuan OEM, and the price difference between the two is not much, but in Zhongchuan's independent products, there are more cost-effective 002 polyurethane condoms to choose from.
 
Zhongchuan condoms, like Sagami and elephants, use avocado packaging boxes, add water-based lubricants, divided into 5 and 11 packs, and the average price of 002 single piece is 8 yuan, which is slightly cheaper than Okamoto and Sagami.
 
In terms of quality, Nakagawa's sleeve fit is slightly worse than Okamoto 001, there will be a little wrinkles when used, and Nakagawa's size design is slightly wider, if you feel that Nissan polyurethane condoms are too tight, it will be more suitable to buy Nakagawa.
