The handmade soap class of the Prison has been established for 13 years since 2006. With the short-term technique training, the Prison manufactures basic equipment. We extract perfume from the citronella and rose that the horticultural squad plants on the kitchen site to manufacture molded soaps with special fragrance. We use the soap we produce in the bathrooms in the Prison. After seeing some results, we established it as a manufacturing item in the self-run business. The main customers of the soap include the inmates and employees in the Prison, and prisons around Taiwan. The Prison continues to develop new formulas for the product. The soap we produce is suitable for daily use and economical. We are aiming for the public as our customer.
