Founded in 1979, tutuanna is a girly accessories brand specializing in socks and underwear from Japan, and began to open its first Chinese store in Shanghai in 2009. The customer base is mainly aimed at the fashionable young group, through the opening of specialty stores, through the opening of many stores in Japan and Chinese mainland, with a cute and fashionable style in the hearts of consumers to establish a clear image.
 
Tutuanna's wool socks come in a wide range of styles, from boat socks to pantyhose, but the common problem is that the wool content is not high, usually below 11%, and the texture of wool is mimicked by adding acrylic blends. The texture of acrylic is similar to that of wool, but the air permeability is far inferior to that of wool, and it is easy to produce peculiar smell when worn for a long time, and the pilling situation is also more obvious.
 
The price of Tutuanna wool socks ranges from 19 yuan to 49 yuan per pair, which is relatively expensive in chemical fiber socks, but Tutuanna has always won by appearance, and the choice of colors and patterns is very diverse.
