Hengan is one of the two major hygiene products companies in China, and the other is Guangdong Jingxing Health Care Industry Co., Ltd. Guangdong Jingxing's ABC and Free fly are all over the provinces and cities in China, and are also sold to Southeast Asian countries. Its ABC was launched early, biased towards mature women, focusing on a cool experience, while Free Fly, which was born in 2004, pays more attention to the girl group, and comfort is more important. According to the Nielsen report, in 2015, the two brands jointly occupied nearly 11% of the market share of China's supermarket channel.
 
It is also a brand for girls, Seven Degrees Space has a high-end palm pad series and affordable girls' pad series, once again subdividing the crowd and guarding the mid-to-high-end line, while Free Fly only has affordable models, which are not rich enough in the product series.
 
Free Fly Outer is packed in a sealing strip bag, with the best sealing, and the overall design is also more in line with the girl's positioning. Free Fei has two types of sanitary pads, ultra-thin active and active blue, both of which are soft surfaces, and the length of the towels is 152mm, of which the price of a single piece of ultra-thin active pads is about 0.2 yuan, and the 0.5mm ultra-thin towel body has good air permeability in daily use. Active blue pads are 0.2mm thicker than ultra-thin active, can absorb more liquid, and are recommended to be used when there is more secretion, the price of a single tablet is 0.3 yuan, and there is still a problem of insufficient viscosity.
 
On the whole, the cost performance of Free Fly sanitary pads is not high, and both are fragrance pads, which can be avoided by women who are prone to allergies.
