Nueve veces nueve or 9v9 was launched in 2015 by Florencia Castillo as a permanent collection of sustainable knitwear.

She forged her identity by finding pleasure in creating patterns and garments, which she combines with knitting techniques. Her current collection is made from high-quality 100% pure Italian merino wool. Since 2019, she has been living with her family in Bern, where she continues her work under the name 9V9
