The beauty sewing agent market is still very young, except for a few large factories focusing on this, most of the famous manufacturers are the original big brands in the decoration and building materials industry. Submarine is one of the most concerned floor drain brands in China, and the participating unit of the national standard for floor drain has also expanded the product line to the beauty sewing agent. Due to the fact that there is basically no subdivision of the sewing agent at present, the submarine has not launched too many products like many manufacturers, and there is only one "Mandarin Duck sewing porcelain" on the market.
 
There are a total of 12 colors of Mandarin Duck sewn porcelain, and the choice is moderate, including mainstream black, white, gold, and silver, but there are no gray products, and the colors are relatively bright. At present, the homogenization of the sewing agent is very serious, and the submarine is no exception, and the product features can be basically classified as "porcelain enamel texture", due to the material advantages of epoxy resin, waterproof, mildew-proof, and wear-resistant performance are good. At present, the price of Mandarin Duck beauty sewn porcelain is about 120 yuan, which is also relatively mediocre.
