Shenzhen Qixin Co., Ltd., referred to as Qixin Group, is a service provider that provides enterprises with modern office solutions, and is one of the largest comprehensive office stationery enterprises in China, just like Deli Group. Qixin's products cover more than thousands of kinds, focusing on office stationery, not professional pen factories, and Chenguang Zhencai Baixue and other three major professional pen manufacturers still have a certain gap in strength.
 
Qixin has been rated as "China's Top Ten Stationery Brand Enterprises" by China Cultural, Educational and Sporting Goods Association for seven consecutive years, and in 2006, the cultural management products were awarded the title of "National Inspection-free Products", leading and participating in the formulation of more than 10 national standards and industry standards, in terms of quality as a whole, in line with the standards, but compared with similar brands, there is no obvious advantage.
 
There are not many product lines of Qixin, bullet GP003, GPP009 and Deli are similar, there is nothing special. The shape of the needle K35 is similar to the Chenguang design, and the pen clip is tight, so you don't have to worry about rolling off the table. The grip comfort of the gel pen is good, but the internal structure is not reasonable enough, resulting in a very weak feeling when pressed, and even a situation where it cannot be pressed.
 
The refill of the K35 needle tube is a decent 0.5mm writing diameter, no scratching, the smoothness is the best one in the heart, the ink is full, quick-drying and waterproof, which can be compared with the Japanese pen, the price is about two yuan, it is a high-yield gel pen with more stable quality, and the writing feeling is also better.
