Kokuyo, which has a mediocre reputation in China's stationery industry, is a leading company in Japan's stationery industry, similar to Chenguang and Deli's status in China. KOKUYO first took root in the paper products manufacturing industry, and then slowly expanded its product line to become the largest comprehensive office supplies supplier in Japan.

KOKUYO's current strong areas are notebooks, adhesive tapes, document management products, and office space design, among which the Campus series of notebooks, which first entered the Chinese market, are still selling well. KOKUYO's office furniture business was largely unknown in China until 2008, when KOKUYO became an office space design service provider for the Beijing Olympics and an exhibitor at the Japan Industrial Pavilion at the Shanghai World Expo in 2010.

KOKUYO mechanical pencils are produced in response to the needs of expanding the product line, and naturally cannot squeeze into the first echelon in the Japanese system, and the product itself is not high in technical content, but the quality is acceptable, and it is suitable for primary and secondary school students. Similar to Rakudo, KOKUYO's writing mechanical pencils resemble graphite pencils in shape, but they don't have the high-quality sense of logs, and the craftsmanship is much rougher than that of Rakudo.

The ProteXin series of drawing mechanical pencils is much more advanced than writing mechanical pencils, and can even be compared with other brands. The biggest selling point of this pencil is that when the wear of the core is shortened, the tip automatically retracts to reveal the core, which can reduce the number of presses. In terms of appearance, the ProteXin pencil is not inferior to the Mitsubishi pencil's mechanical pencil, but it is still slightly inferior in terms of grip and nib perspective, but the price of KOKUYO is dominant, and the price is around 30 yuan, and other mechanical pencils with similar technology do not have such an affordable price.
