Lennon Tool Bar was founded in 2014 at Tamsui, Taiwan. Initially, it started to promote arts and crafts of Indigo Dyeing, a business that flourished a century ago in Taiwan, and at the time, Taiwan exported a considerable amount of "doroai," or the raw material of colorants used in Indigo Dyeing, to the Japanese Empire. Lennon Tool Bar draws inspiration from the traditional process and the popular colors used in Indigo Dyeing.
